Windows: 386SX 1MB 4MB 8MB
Macintosh: 68030 2MB 4MB 8MB
UNIX: N/A 3MB 16MB 16MB

What type of modem do I need to use Netscape Navigator?
We recommend using a 14.4-Kbps (or faster) modem. Netscape Navigator will also work at 9600 bps.

What type of Internet account/Access do I need to use Netscape Navigator?
To make the best use of Netscape Navigator, your service provider must allow access to the many World Wide Web servers on the Internet through a SLIP or PPP account. (PPP is a newer protocol and is considered better than SLIP). Talk to your Internet provider if you are unsure about your available access capabilities.

Netscape Navigator works with either SLIP or PPP Internet access protocols.

What other software do I need to use Netscape Navigator?
Netscape Navigator for Windows requires a Winsock TCP/IP stack; the Macintosh version requires MacTCP. Depending on your method of access to the Internet, other utilities may be required. Your Internet access provider can fully explain particular software needs and help you configure your system for Netscape Navigator.

Once installed and configured, Netscape Navigator is a fully integrated Web browser, newsgroup reader, and FTP utility.

While not required to run, Netscape Navigator uses various "helper applications" for displaying audio, video, and other types of files. Options for using these applications can be configured in your Preferences window. For help configuring this window, take a look at our on-line manual documentation.

What helper applications exist and where can I get them?
On the Macintosh: StuffitExpander, JPEGView, SoundMachine, SoundApp, MacBinaryII+, Mactar, MacGzip, and Sparkle are all downloadable applications. There are several popular FTP sites for Macintosh software, including ftp://sumex-aim.stanford.edu and ftp://wuarchive.wustl.edu. You can look at the Macintosh Helpers page for more information.

On Windows: LVIEW31.EXE (for JPEG images), MPEGPLAY.EXE (for MPEG movies), and MPLAYER.EXE (for audio files) are all useful applications. The main site for these is ftp://ftp.cica.indiana.edu.

Depending on the UNIX platform on which you are running X, you will need to use different applications. See our UNIX Helper Applications document for more information.

You can also find an evolving list of sites with helper applications under Helper Applications.

All helper applications are configured through the Preferences panel under the Options menus. For more information, check the documentation in our on-line manual.

NETSCAPE NAVIGATOR FEATURES

Does Netscape Navigator offer integrated e-mail and newsgroups?
You can get more information about Usenet news in our Helper Applications documentation.

If you already have an account on a mail server (ask your network administrator or Internet service provider), then Netscape Navigator will allow you to send Internet e-mail directly from the browser window; you cannot read or receive mail in Netscape Navigator and should continue to use your normal e-mail program for those functions.

Does Netscape Navigator support signature files?
Version 1.0 does not support signature files; version 1.1 does support signature files.

Does Netscape Navigator support real-time, on-the-fly decoding of audio or video files?
The X Window System version of Netscape Navigator can download a file by either waiting until the entire file is received and then launching the external helper application or by launching the external software and sending data to the helper app as it arrives from the network. The Windows and Macintosh versions only support the former method.

If you have a program on your X Window platform that can accept streaming audio input (there is currently no program for streaming video), it can be used to listen to audio streaming in from Internet in real time. Check out our page on how to configure helper applications for more information.

Why do my images come out with dots or speckles on them?
Netscape Navigator offers in-line image support for GIF, JPEG, and XBM (X bitmap) formats, so you can view displayed images in place, as the page author intended, without relying on a separate or additional utility or helper application.

Netscape Navigator's routines for displaying images rely on technology that intelligently translates image colors (when necessary) into those available on your system. If your system's color support doesn't match that of the image, images may look speckled.

You can turn off dithering in the Preferences dialog box under the Options menu; JPEG images, however, will always be dithered.

How does document caching work in Netscape Navigator?
Netscape Navigator uses a memory cache for encoded images and text; you can configure the size of this cache in the Preferences dialog box under the Options menu. The cache is persistent, meaning that files are kept locally on your machine for fast browsing. You can clear the cache at any time in the Cache and Network dialog box under Preferences in the Options menu.

If you click on a link to a page that is in the cache, Netscape Navigator checks with the server to see if the page has changed before pulling it from the cache. (If it hasn't, the page is not downloaded and the memory cache version is used.)

The Verify Document option on the Cache and Network preferences pane may be used to control how often the server is re-checked.

If you use the Back button to go to a page, however, you will access the version in the memory cache. This makes sense: If you want the latest version of a page, click on the link; if you want the last version you saw, use the View History option under the Go menu.

Why doesn't Netscape delete all of these files in its ``cache'' directory when it exits?
See the preceding question; the Netscape disk cache is a persistent cache. It is used to cache documents across sessions of the Navigator, so that you will not need to re-download a page which has not changed even if you don't visit it until days later.

The maximum amount of space consumed by the disk cache is controlled from the Cache and Network pane of the Preferences dialog. Set it to the largest amount of disk space you feel comfortable devoting to this purpose (or 0) and then just ignore the cache directory. When the cache reaches its limit, new documents will push old documents out of it: the most recently accessed document will be removed, and should that document be visited again, it will be re-fetched from the network.

Is there a way to import hotlists from NCSA Mosaic as Netscape Navigator bookmarks?
Yes! Netscape Navigator bookmarks come with an Import command that will read any HTML file containing links and turn those links into entries in the bookmarks list. Convert your current hotlists to HTML and then click the Import option in the View Bookmarks window. (If you need help, read through our documentation regarding the Bookmarks dialog box)

If you are running NCSA Mosaic for the X Window System, the easiest way to import hotlists into Netscape Navigator is to use the included hot-convert.sh shell script. When you run that script, it will read in your xmosaic hotlist and append the contents to your Netscape Navigator bookmarks file. Then simply restart Netscape Navigator.

You can also bring up your hotlist dialog box in NCSA Mosaic for the X Window System and choose the Mail To command. Mail the hotlist to yourself; it arrives in HTML format. In addition you can use the hl2html (that is, "hotlist to HTML") utility to convert your hotlist to HTML.

If you're using NCSA Mosaic for Windows, use the WinH2htm (Windows hotlist to HTML) utility.

If you're using NCSA Mosaic for Macintosh, there is a utility called HHConv, a HyperCard stack that will take you through the process of turning your hotlist into HTML.

Does Netscape Navigator support XPM (X Pixmap) images?
No, Netscape only supports GIF, JPEG, and XBM internally. Other image formats can be viewed externally by configuring an appropriate helper application.

Why do I get the error panel, "Cannot connect to host"?
This error might have several causes, including any of the following:
  1. Your system might be behind a firewall. If it is, you need access to a SOCKS or proxy server to connect to an Internet host. Check with your network administrator to get the details of the SOCKS or proxy server being used.
  2. The host you are trying to connect to may be down.
  3. You may be having problems with your SLIP or PPP connection. Contact your Internet service provider or network administrator.
  4. If you are on a Windows machine, your Winsock may not support asynchronous DNS, so you should try changing the line

    ASYNC DNS = YES
    to
    ASYNC DNS = NO

    in your NETSCAPE.INI file.

Why can't Netscape Navigator sometimes look up Internet hosts?
This can happen if your computer or workstation is behind a firewall and your system administrator has configured your network in a fashion that doesn't allow Netscape Navigator to communicate with outside networks.

In an X Window System environment, Netscape Navigator may sometimes fail to look up hosts because your system uses YP/NIS exclusively for hostname mapping or your system administrator doesn't allow DNS lookups to work through your firewall. (Netscape Navigator requires the standard DNS name service for it to translate host names to IP addresses. If your site does run DNS somewhere, you can use a workaround by specifying the host that has the DNS information in the socks_ns environment variable. Note that the specification must indicate the IP address of the host, not its name.)

Netscape Navigator for SunOS 4.x currently includes two sets of executables - one that uses YP/NIS and one that uses DNS only.

On the Macintosh, take a look at MacTCP 2.0.6 documentation.

Does Netscape Navigator support SOCKS?
Yes, Netscape Navigator supports version 4 of SOCKS. It uses the protocol as defined by the socks.cstc.4.1 implementation.

You can set the SOCKS host by opening the Preferences window under Options, selecting the Mail and Proxies page, and editing the SOCKS host and SOCKS port number. Restart Netscape Navigator after doing this (the options will save automatically). There is a limitation in the current implementation - Netscape Navigator doesn't understand the @ syntax present in SOCKS configuration files.

In the 1.0 Windows version, the SOCKS host can only be specified in the INI file. The format in the INI file is:

[Services]
SOCKS_Server=mysocks.domain.com

In Windows version 1.1, the SOCKS proxy can be set under the Proxies option in the Preferences dialog box under the Options menu.

Does Netscape Navigator support proxies?
Yes. You can choose the proxy host by selecting the Preferences option under the Options menu. Once the Preferences window appears, select the Proxies page and enter the list of proxy hosts and port numbers. Don't forget to save your options. The proxy should be in effect for the next request.

Why do I have to re-enter my user ID and password for the proxy with each HTTP connection I attempt to make? Shouldn't this information be retained for the entire session?
Ideally, the client should not be able to authenticate itself to the proxy server using HTTP username/password authorization, because only one authorization response can be sent in any one request. It is therefore impossible for the client to authenticate itself to both the proxy server and a server beyond the proxy. If you want to authenticate your proxy users, you must use IP-address authentication.

Some other browsers allow you to perform your access authorization without re-entering the ID and password - but this could constitute a security risk.

I have more than 100 entries in my bookmarks list and the pull-down menu goes off the bottom of the screen. Is there a way to set the number of bookmarks displayed?
No. You can, however, adjust the layout of the bookmarks list by creating categories.

Bring up the View Bookmarks dialog box. Position your cursor above the first bookmark you wish to categorize and click on New Header to insert a bolded subject header in the list. In the text field to the right, give it a name. Next, select the bookmark under the new header and click on the large Up arrow; the bookmark will indent to show you that it's now active under the new header. Continue on down the list, selecting and clicking on the Up arrow, indenting all the bookmarks you want under that subject header. Repeat this process for all your bookmarks, adding subject headers where appropriate. When you're done, close the View Bookmarks window. When you next hold down the Bookmarks menu option above the main browser window, you should see a list of your new headers with arrows indicating the submenus that contain your individual bookmarks.

Is it possible for me to save an image that is part of an HTML page that I'm viewing?
Netscape Navigator 1.0 does not support this. Version 1.1 has a new pop-up menu that allows you to save an individual image. To access the pop-up menu on the Windows or X Window platforms, press and hold down the right mouse button over an image. On the Macintosh, hold down the mouse button for about one second and the pop-up menu will appear.

Is there a way to include document text from a Web page in either indented or nonindented styles while mailing it from Netscape Navigator?
Yes. Simply click the Include Document Text button in the Mail Document dialog box under the File menu. Each line of text will be indented and preceded by a right carat (>).

In Netscape Navigator for Macintosh, you can alternately select Text in the Mail Document window's Attach pull-down menu. This option will MIME encapsulate the text with Content-Type: text/plain, giving the user on the other end the ability to extract the original, unaltered document.

In Netscape Navigator for the X Window System, you have the option of using Attach: Text, Attach: Source, or Attach: PostScript.

Do you have a TCP/IP stack built into Netscape Navigator?
No.

Where can I find a list of known bugs for Netscape Navigator?
Release Notes for Netscape Navigator for Windows and Netscape Navigator for X Window System can be accessed from the Help menu.

Netscape Navigator for Macintosh makes the Release Notes available under both System 7's Balloon Help and Netscape Navigator's Help menu.

What HTML extensions are available in Netscape Navigator?
Netscape has many HTML extensions available for Netscape Navigator.

How do I get WAIS requests to work with Netscape Navigator?
You must use a WAIS proxy. Open the Preferences window under the Options menu and select Proxies to set your WAIS proxy.

The CERN httpd proxy server supports WAIS; if you use it to get through your firewall, you can use WAIS URLs under Netscape Navigator. In addition, you can use it as your WAIS proxy even if you don't have a firewall.

Also note that WAIS is generally accessed through a gateway. WAIS, Inc., for example, gives its customers gateway software. You can also find out more information about freeWAIS.


NETSCAPE NAVIGATOR FOR WINDOWS

Does Netscape Navigator work with Windows NT?
In our tests, Netscape Navigator version 1.0 works with Windows NT 3.5 (except on DEC platforms). All versions of Windows NT are supported under Netscape Navigator version 1.1.

Does Netscape Navigator work with Windows for Workgroups?
Yes. We have tested Netscape Navigator with Windows for Workgroups 3.11. Please note that the Wolverine TCP/IP stack doesn't support a dial-up connection to the Internet.

How can I specify the SOCKS host for Netscape Navigator for Windows?
In the 1.0 Windows version, the SOCKS host can only be specified in the INI file. The format in the INI file is:
[Services]
		SOCKS_Server=mysocks.domain.com
In the 1.1 Windows version, the SOCKS proxy can be set using the Proxies option in the Preferences dialog box under the Options menu.

Which Winsock software does Netscape Navigator for Windows work with?
Netscape Navigator should work with any Winsock 1.1-compliant TCP/IP stack, including the following:

  • Trumpet Winsock 2.0e
  • FTP Software PC/TCP
  • Network Telesystems TCP Pro
  • NetManage
  • Microsoft Windows For Workgroups (Wolverine) (Note: This software doesn't support modem connections to the Internet)
  • Microsoft Windows NT

We've heard particularly positive reports from customers using the Trumpet Winsock 2.0e, available at ftp.cdrom.com/.22/cica/winsock/ and ftp.trumpet.com.au/ftp/pub/winsock/. Download the file called twsk20e.zip (or twsk20b.zip in the case of ftp.cdrom.com).

Can I use the INI files from my NCSA Mosaic for Windows with Netscape Navigator for Windows?
Yes. You can copy your MOSAIC.INI file to a NETSCAPE.INI file.

When you do this, however, watch out for a few things: Be sure to add fields for History File and File Location. Be sure to convert your NCSA Mosaic Hotlist entries to Netscape Navigator Bookmarks.

NETSCAPE NAVIGATOR
FOR THE X WINDOW SYSTEM

How do I set the default window size for the X version?
Use the command-line option
        -geometry =620x950+630+40 

or the X resource
        Netscape.TopLevelShell.geometry: =620x950+630+40 

How do I make a mailcap file or a MIME file for the X Window version of Netscape Navigator?
This document explains all there is to know about mailcap files. On a related subject, check out our documentation on Mime Types.

Why does Netscape Navigator complain about my $DISPLAY setting? Other programs don't have these problems.
This could be due to DNS/YP problems. The $DISPLAY variable contains a hostname, and it's possible that Netscape is having trouble looking up that host name. Try using the IP number of that host in your $DISPLAY setting rather than the hostname.

How do I get rid of this warning about a `` Character not supported in Font''?
The warning in question looks like
      Warning:
        Name: toText
        Class:XmTextField
        Character 'c', not supported in Font. Discarded.

This is a bug in some versions of the OpenWindows X server that causes it to pick fonts which are only 1 pixel high, making text fields unusable. We do not yet know of a reliable workaround.

Why does the AIX version of Netscape Navigator fail to start with errors about _XmStrings undefined?
This version of Netscape Navigator was linked against AIX X11R5 and Motif 1.2. You are probably running X11R4 and/or Motif 1.1. The suggested solution is to upgrade to a more recent version of the operating system.

Why does Netscape crash every time I try to copy or paste in one of its text fields?
On some systems, we linked Netscape against X11R5. If your system is not running X11R5, then you need to install the R5 ``nls'' directory before any R5 program will be able to copy or paste without crashing: this is a bug in R5 itself.

When you started Netscape, it should have printed this message to stderr:

If you install that directory, copy and paste to or from Netscape (or any other R5 application) should work fine.

Why doesn't my Backspace key work in text fields?
By default, Linux and XFree86 come with the Backspace and Delete keys misconfigured. All Motif programs (including, of course, Netscape Navigator) will malfunction in the same way.

The Motif spec says that Backspace is supposed to delete the previous character and Delete is supposed to delete the following character. Linux and XFree86 come configured with both the Backspace and Delete keys generating Delete.

You can fix this by using any one of the xmodmap, xkeycaps, or loadkeys programs to make the key in question generate the BackSpace keysym instead of Delete.

You can also fix it by having a .motifbind file; see the man page for VirtualBindings(3).

Note: Don't use the *XmText.translations or *XmTextField.translations resources to attempt to fix this problem. If you do, you will blow away Netscape Navigator's other text-field key bindings.

Why does Netscape take so long to start under XFree86?
One possible reason could be that you are using scaled fonts. If you have Type1 or Speedo fonts on your font path, then the first time those fonts are accessed, the X server will need to convert them from outlines to bitmaps. This is a CPU intensive task, and if your machine doesn't have floating-point hardware, it can take a long time. A workaround is to change your font path to have the Type1 and Speedo fonts at the end of the path. This will cause the X server to use the 100dpi or 75dpi fonts instead, which are bitmapped and don't require expensive conversion.

Can I use Netscape with FreeBSD 1.1?
We have been told (but have not verified) that the BSDI binaries will work on x86 systems running FreeBSD 2.0, but not FreeBSD 1.1.5.1. However, your friendly neighborhood kernel hackers have come up with a set of kernel patches to FreeBSD 1.1.5.1 which alegedly allow Netscape to function. This is all at your own risk, of course, but check out Peter da Silva's archive of FreeBSD Netscape patches.

I have an external viewer that produces a lot of output, and the subprocess diagnostics window keeps popping to the front. How do I make it stop?
The best solution is to force the external viewer to not produce so much output. A well-written viewer will have an option to produce only real errors as output rather than always produce diagnostics that cannot be suppressed.

The mpeg_play program is particularly troublesome. You can solve it by changing your .mailcap file entry from

    video/mpeg; mpeg_play %s
to
    video/mpeg; mpeg_play %s >/dev/null 2>&1

This will instruct mpeg_play to discard all of its diagnostic output.

Why were the X resources for the ``history'' and ``bookmarks'' files removed?
They weren't: they were just moved. Rather than X resources, the locations of those files are now settable via the Applications and Directories pane of the Preferences dialog.

The .netscape-preferences file must always be under $HOME, but Netscape's other files may be placed anywhere.

How do I cause Netscape to re-read my .mailcap and .mime.types files after I have edited them?
Simply bring up the Preferences dialog and press OK; those files are re-read each time the preferences are changed.

Netscape uses up all of the colors in my colormap, how do I make it stop?
There are two ways: the first is to use the -install command-line option (or the installColormap resource) to cause Netscape to install a private colormap instead of using the default, shared colormap. Netscape's image quality will be high, but, depending on your system, this may cause unattractive colormap flashing when changing focus between Netscape and other applications.

The second way is to use the -ncols command-line option (or the maxImageColors resource) to limit the number of color cells Netscape will attempt to allocate. The lower the number, the lower the quality of images displayed in Netscape, but the more cells will be left for other applications. 200 is probably a good choice. The default is 0, meaning Netscape will allocate as many colors as it can.)

How do I get rid of this warning about an ``Illegal mnemonic character''?
The warning in question looks like
      Warning:
        Name : menuBar
        Class: XmRowColumn
        Illegal mnemonic character; Could not convert X KEYSYM to a keycode

By default, Motif binds the key F10 to a command that activates the menubar. Unfortunately, if your keymap doesn't contain an F10 keysym, Motif will whine at you about it instead of doing the sensible thing and simply ignoring that binding.

The easiest workaround is to use either the xmodmap or xkeycaps programs to make there be an F10 key on your keyboard somewhere. Just pick some other function key that you don't use and put it there...

What command-line options are supported in the X version?
Starting Netscape with the -help flag will list the other options. In addition to the standard X options, these options are supported:

-help to show this message.
-version to show the version number and build date.
-display dpy to specify the X server to use.
-geometry =WxH+X+Y   to position and size the window.

How do I get rid of this warning about ``Actions not found''?
The warning in question looks like

The problem is that there is junk in your resource database: an invalid resource setting has been made. It would appear that the most common cause of this warning is that BSDI 1.1 comes with a sample resource file which contains the aforementioned illegal setting. On the BSD/OS 1.1 CD-ROM, the default .Xresource file (from /usr/share/skel/) contains these lines:

    ! definitions for the Text widget
    *Text.Translations:             #override \

            Button1<Btn2Down>:      extend-end(CLIPBOARD)\n\
            Ctrl<Key>W:             delete-previous-word()\n\
            Meta<Key>k:             kill-selection()\n\
            Ctrl<Key>U:             beginning-of-line()\
                                    kill-to-end-of-line()\n\
            Meta<Key>u:             unkill()\n\
The parts mentioning Meta<Key>k, Ctrl<Key>U, and Meta<Key>u are illegal. If you have similar lines in your resource files (.Xresources or .Xdefaults), delete them.

How do I get Netscape to work with TERM (a pseudo-SLIP implementation) under Linux?
The most reliable method we have heard of is to run a termified HTTP proxy server locally, and configure Netscape to talk to that proxy via the Preferences dialog.)

Some people have success using the termify program to modify the Netscape executable to speak to TERM directly, but it doesn't work for a lot of people, and we do not recommend it.

You might consider looking in to TIA (``The Internet Adapter'', a commercial product from another company with whom we are not affiliated) for what appears to be a more robust solution to the problems that TERM attempts to solve.

Why does the SGI WebForce version of Netscape display my images in 8-bit even though I have a 24-bit screen?
Other versions of Netscape will, by default, choose the ``best'' visual which a screen supports, and use that. However, at SGI's request, we made the WebForce version of the SGI executable (the one with the SGI logo in the corner instead of the Netscape logo) always use the default visual instead. So, if you have a 24 bit screen, but the default visual is 8 bit, Netscape will use that unless you specify the command-line option -visual best.

Why does the SGI version of Netscape generate X errors when I save files?
If you are running Netscape on an SGI machine, and you have turned on the SGI-specific sgiMode and useEnhancedFSB resources, and Netscape is running on a non-default visual, then X errors (BadMatch) will be generated any time a file requester window is used.

This is a bug in SGI's extensions to their Motif library, and only occurs if all of the above conditions are met. The only side-effect of those error messages is that the popup menu on the file requester doesn't appear. Other than that, they are ignorable.

If you don't turn on useEnhancedFSB, or if you use the default visual, this problem will not appear.

Rumor has it that SGI has fixed this bug, but that the fix was not done in time for Irix 5.3. Perhaps they have a patch for it by now.

How do I set up default preferences for all new users at my site?
The first time a user runs Netscape, a .netscape-preferences file will be created in their home directory, and that file will be used for all future sessions. So, the easiest way to set default preferences (like proxies and socks hosts) is to cause that file to be created with the right contents before the first time each user runs Netscape for the first time. An easy way to do this is to create a ``wrapper'' shell script around the Netscape executable, like the following:

To create the default preferences file, simply run Netscape once, set the preferences, quit, and copy the .netscape-preferences file that was written in your home directory. You will then need to edit that file and remove all of the user-specific lines. This is important! In particular, remove the lines containing your name and email address, and any lines referring to files in your home directory (the history and bookmarks files, the newsrc directory, the signature, the cache directory, and the personal MIME types and mailcap files.)

Bear in mind that it is not currently possible for multiple users to share the same bookmarks, cache, or history files.

The cache directory should go in some directory owned by the user: /tmp/ is not a good choice, since that is shared by multiple users, and on some systems, is cleared at each reboot (which would make the persistent disk cache worthless -- it would then be non-persistent!) If you want to disable the disk cache by default, simply set its size to zero in the preferences.


NETSCAPE NAVIGATOR FOR MACINTOSH

Is there a native PowerPC version of Netscape Navigator?
Yes. Version 1.1 can be installed as either 68K, PPC, or fat versions.

Does Netscape Navigator support AppleScript and Drag and Drop?
Version 1.0 supports AppleScript on an experimental basis only; several WWW Apple Events are available in Netscape Navigator's AppleScript dictionary. Version 1.1 supports AppleScript as described in the Netscape Client Application Programming Interface documentation.

Netscape Navigator versions 1.0 and later are recordable.

Drag and Drop is also being integrated. If you are running System 7.5 or have the Drag Manager extension installed, you can drag a URL into the main window, and it will be loaded. (This feature is especially useful if you are using NewsWatcher as your news reader.) You can also drag a URL out of the History window under the Go menu.

Version 1.1 allows you to drag a link out of the Netscape Navigator browser window onto the desktop or into a Finder window. The document referred to by the link you're dragging will be saved to disk.

How do the modifier keys work in Netscape Navigator?
The following modifier keys are supported by Netscape Navigator:
  • Page Up, Page Down, up arrow, and down arrow: for scrolling in the main window
  • Tab keys: to jump to and from form fields
  • Option key: when pressed and clicking on a link, to save the document to disk; and, when pressed and choosing the Open File command, to open any local file (rather than just HTML files)
  • Command-left arrow and Command-right arrow are equivalent to the back and forward buttons and menu commands

What should I do if the Preferences window is too large for my Macintosh screen?
Netscape Navigator's Preferences window is too large to fit on SE/30 or Classic II screens. This will be fixed. For now, you can use the Enter key to save the preferences and Esc to cancel your changes - they will activate the invisible buttons.

Why can't I select text on a grayscale monitor?
All text in Netscape Navigator can be selected. If you're using a grayscale display on a Macintosh, you simply may not be able to see the selection, especially if the color you've chosen for selected text is close to our background color, light gray. You can work around this problem by opening your Control Panels and using the Color window to choose an even lighter color, such as yellow, or a darker one, such as red. Even though these colors map to the screen as shades of gray, they are sufficiently lighter or darker for you to tell when you've selected text.

Why am I getting so many "Unable to locate host" error messages while using Netscape Navigator for Macintosh?
Try upgrading your MacTCP to version 2.0.6. Start at Apple's home page or go directly to the networking software updates.

Why does Netscape Navigator 1.0 for Macintosh generate errors if I click on the Stop button?
This is a known problem with Navigator 1.0. If you press the Stop button while Netscape is looking up a host name, error messages (including "Unable to locate host") are displayed and Netscape Navigator stops working correctly. The workaround is to quit Netscape Navigator and restart it.

This problem is fixed in Netscape Navigator 1.1.
