Netscape has a list of known problems in their online
release notes, please refer to those release notes for
further details. The URL for those problems is:
http://home.netscape.com/eng/mozilla/4.5/relnotes/unix-
4.51.html
Netscape posts a list of currently known Security issues
dealing with the browser. The URL for that information is:
http://home.netscape.com/products/security/resources/notes.html
and is updated as new security issues are discovered.
Other problems that we have found specific to the SGI
release that may also exist in other releases are as
follows:
+o While Netscape documents how to eliminate the use of a
disk cache by setting the cache size to zero, Java,
JavaScript, and Plugins all need local cache files in
order to function properly. A zero size cache will
cause the browser to crash periodically when running.
The workaround is simply to not specify a zero size
disk and/or memory cache, a one meg cache is enough to
work around this problem.
+o When you try to play a movie from a Web page, you may
see this error:
""""SSSSGGGGIIII MMMMoooovvvviiiieeee PPPPlllluuuugggg----iiiinnnn:::: EEEErrrrrrrroooorrrr ddddoooowwwwnnnnllllooooaaaaddddiiiinnnngggg iiiinnnnttttoooo ccccaaaacccchhhheeee.... PPPPlllleeeeaaaasssseeee iiiinnnnccccrrrreeeeaaaasssseeee ddddiiiisssskkkk
ccccaaaacccchhhheeee ((((NNNNeeeettttwwwwoooorrrrkkkk PPPPrrrreeeeffffeeeerrrreeeennnncccceeeessss DDDDiiiiaaaalllloooogggg))))....""""
When this happens, you may need to restart Netscape or
try launching the movie again; the plug-in should work
the second time.
You may also see the following error when the movie
closes:
""""wwwwaaaaiiiittttppppiiiidddd eeeerrrrrrrroooorrrr:::: NNNNoooo cccchhhhiiiilllldddd pppprrrroooocccceeeesssssssseeeessss....
You can ignore this error.
+o When launching multiple instances of netscape from the
same user account on a single machine you will get a
dialog box telling you that a lock file exists. If you
ignore this dialog box then you won't be able to save
anything to the disk cache and plugins will not
function properly. Communicator is not designed to run
multiple instances of the browser for a single user due
to lock contention with the bookmarks file, cache, and
- 2 -
several other databases. It's best to run a single
instance then pop up new browsers from within that
instance using CTRL-N or using the "File->New-
>Navigator Window" menu item.
+o When using U of W IMAP server and the IMAP server is
configured to "Show only subscribed folders" and the
behavior for deleted messages is set to move them to
the Trash folder, you can't delete or rename any IMAP
mail folders. The workarounds are to unset the
preference for "Show only subscribed folders" or
delete/rename the folders manually on the IMAP server.
+o When using U of W IMAP server and the IMAP server is
not configured to "Show only subscribed folders", every
time you restart netscape, the message count is lost
for all subfolders that are three or more levels deep
in hierarchy. The workarounds are to set the
preference for "Show only subscribed folders" or to not
create subfolders more than two levels deep.
+o If you set your Forward mail preference to "Forward As
Inline", your signature will not be included in the
composition even though you have specified a signature
file in your Identity preferences, and the signature
file exists.
+o Dragging a message from your default IMAP server to
your local mail copies the message instead of moving
it. Dragging a message from your default IMAP server
to your other IMAP servers does not work at all.
+o Several of the shortcuts do not work like CTRL+SHIFT-F
(for Find on Internet) though they do work off the menu
bar.
+o Due to some problems in the cache, some HTML pages may
not display properly. To fix the display try hitting
the "Reload" button or hold down the "Shift-key" and
press the "Reload" button to force the reload from the
server. Usually this will cause the page to display
properly.
+o The "Guide" menu and several other buttons are
initialized to access the most current version of these
documents from Netscape Communications Corporation's
World Wide Web site. If you can not access these
sites, make sure that you are not sitting behind a
firewall. Contact your systems administrator for more
information on firewalls and how to configure the
browser to get thru the firewall. If your machine is
- 3 -
directly connected to the Internet, then this will not
be a problem for you.
+o If your system is configured for a Japanese environment
the Xt text entry widget may not function properly.
Try adding the following to your .Xdefaults or
Xresources file to work around this problem:
NNNNeeeettttssssccccaaaappppeeee****pppprrrreeeeeeeeddddiiiittttTTTTyyyyppppeeee:::: NNNNoooonnnneeee
+o If when navigating the web you download an image or
movie and it brings up a save dialog, make sure that
your system preferences for the location of the mailcap
and mime.types files are the correct ones. Very old
Netscape Navigator beta images available on the network
saved preferences for the location of the mailcap and
mime.types files as "/usr/local/lib/mosaic". This is
the incorrect location and will cause several players
not to run properly. User's must verify that the
system defaults for the mailcap and mime.types files
are pointing to "/var/netscape/communicator". Making
this change will most likely cause the player to
function properly.
+o If when viewing images using the external imgview
viewer you get an error dialog saying it can't open a
file "-nofork" then you have an older version of the
ImageTools. You will need to up upgrade to IL version
3.1 or later. This product is available on SGI's
software download site on the web.
+o There are some cases of DNS lookup when the separate
dns_helper application isn't used. In these cases a
failed DNS lookup will hang the rest of the application
waiting for a timeout from the lookup.
+o Using arrow keys in the compose window's pulldown menu
will cause a crash.
+o There are still a few times when the mail summary file
will get corrupted and launching Communicator to read
mail will crash. In these cases it's best to remove
the $HOME/nsmail/.*.summary file and let the mail
client recreate the summary files. For the most part
this is fixed in 4.51 but if the summary file is
already corrupted then it may cause a crash.
+o When mouse dragging over the pulldown bookmarks menu,
the line separators will sometimes vanish and repaint
themselves.

+o With lots of mail messages or very large mail messages
the reader starts slowing down.
+o If the user created mail folders without using the
Message Center but the Unix shell instead, then
Netscape won't see these new folders. Either always
use the Message Center to create mail folders or use
the script /var/netscape/communicator/fix_nsmailfdir to
fix the mail folder periodically.
+o If you are on a slow network link like a PPP connection
and have the Mail window open and your link goes down,
Communicator can't recover from the disconnect and
hangs.
+o If your ~/.netscape/preferences.js file becomes
corrupted then Communicator may crash on startup. Look
at that file and verify that all directives are on a
single line with no newlines in any ()'s.
+o When using U of W IMAP server, clicking the Stop button
to interrupt the transfer of a mail attachment will
cause the IMAP server process to die. The next time
you click on Get Msg to retrieve new mail, the IMAP
server process will restart, but message status changes
to your folder since the last time the folder was
updated will become lost; deleted messages will come
back, read messages will become unread, etc.
+o Some Netscape plugins may cause corruption of the
$HOME/.netscape/plugin-list. Look at the URL
about:plugins to see which plugin might have corrupted
the plugin list. To workaround the problem, try
removing the plugin and the $HOME/.netscape/plugin-
list, start up Netscape and verify that the plugin-list
file isn't corrupted, then reload the plugin and
restart Netscape.
+o If the user's home directory is NFS mounted from
another machine and the user logs out, the client
process may not get killed and may need to be killed by
hand.
+o None of the Composer plug-ins included with Netscape
Composer are localized for the languages included in
this version so the menus show up as:
CCCChhhhaaaarrrraaaacccctttteeeerrrr TTTToooooooollllssss ---->>>>
HHHHTTTTMMMMLLLL TTTToooooooollllssss ---->>>>
IIIInnnnsssseeeerrrrtttt ---->>>>
LLLLaaaayyyyeeeerrrrssss ---->>>>

+o There is a memory leak problem when a text input field
is used in a CGI web page. Once text is entered into
the text field that causes scroll bars to be rendered,
clicking inside and outside the browser window
repeatedly will trigger the memory leak and cause the
browser to grow uncontrollably.
