You ran into the nasty IRIX 4.0.5 XView bug ::::: ;-<

You will probably have to specify -Wfsdb with every execution of mailtool.

If you have the XView sources at hand you might apply the recently posted
patch from Huw Lynch <[e-mail]> which I append below and
put the resulting libraries into $OPENWINHOME/lib.

Here comes my recent posting ---------------------------------

For all of you still struggling...

Since some of you have been asking, here is how to circumvent the
XView-4.0.5 bug:

THE BUG:
   Any XView application run under the IRIX 4.0.5 Xsgi X11-server
   will lock the Server on first mouse click and no more release
   it until killed from somewhere else.

SOLUTIONS:
  a) Run the application with '-Wfsdb' on the command line. Alternatively
     you could use '-fullscreendebug'.

  b) If you have the sources, add

         extern int fullscreendebug;

     e.g. before main() and

         fullscreendebug = 1;

     after the xv_init(...) call. This forces the program to set this
     flag in any case - also when run with non-xview-buggy servers. But
     it releases you of the danger of omitting -Wfsdb and locking your
     screen.

  c) ONLY, if the program uses the 'fullscreen' package, you might add

        Fullscreen.Debug: True

      in $HOME/.Xresources or specify this resource on the command
      line.  This flag currently disables grabs in both the 'window'
      and the 'fullscreen' package, but is only set from resources
      in the 'fullscreen' package.

Subject: XView 3.0 Irix 4.0.5 & No-Locale Patch

SUBJECT : XView 3.0 patch file that :

      1. stops XView 3.0 hanging Irix 4.0.5 servers for _all_ client
             architectures.

      2. For architectures that do not have OsHasLocale defined as YES
             in XView.cf it reads the resource files XView and <xv_app_name>
         from the system app-defaults file.

This is not a patch specifically for Irix machines, all architectures should
use it (especially those that are networked to Irix machines and those
that do not have OsHasLocale defined).

Action 1 is activated _only_ when the server identifies itself as a
    "Silicon Graphics" version 4 server. When the buggy server is
    detected the -Wfsdb option is forced (which fixes the problem).

Action 2 is automatically activated and configured when OsHasLocale is
      defined as NO in config/XView.cf. Naturally the <xv_app_name>
    resources are given priority over those in XView and both have
    lower priority than the command line and defaults loaded on the
    server.

Files affected :

    xview3/lib/libxview/server/server.c
    xview3/config/XView.tmpl

To apply this patch do the following...

cd <top of the XView 3.0 distribution>
patch -p -s < <this file>


This patch must be applied after the 2 official patches (Patch-01 & Patch-02).

By,

Huw Lynch
