Hi, Rodney - Are these problems new with 21.4.20, or did older versions exhibit the problems, too?

Do you have any motif patches installed? Quoting from the PROBLEMS file:

** Motif Motif is the X11 version of the Gnus torture test: if there's a way to crash, Motif will find it. With the open source release of Motif, it seems like a good idea to collect all Motif-related issues in one place. You should also look in your OS's section, as it may not be Motif's fault. and *** XEmacs crashes on exit (#2) Especially frequent with multiple frames. Crashes that produce C backtraces like this: #0 0xfec9a118 in _libc_kill () from /usr/lib/libc.so.1 #1 0x77f48 in fatal_error_signal (sig=11) at /codes/rpluim/xemacs-21.4/src/emacs.c:539 #2 <signal handler called> #3 0xfee929f4 in XFindContext () from /usr/openwin/lib/libX11.so.4 #4 0xfee92930 in XFindContext () from /usr/openwin/lib/libX11.so.4 #5 0xff297e54 in DisplayDestroy () from /usr/dt/lib/libXm.so.4 #6 0xfefbece0 in XtCallCallbackList () from /usr/openwin/lib/libXt.so.4 #7 0xfefc486c in XtPhase2Destroy () from /usr/openwin/lib/libXt.so.4 #8 0xfefc45d0 in _XtDoPhase2Destroy () from /usr/openwin/lib/libXt.so.4 #9 0xfefc43b4 in XtDestroyWidget () from /usr/openwin/lib/libXt.so.4 #10 0x15cf9c in x_delete_device (d=0x523f00) are caused by buggy Motif libraries. Installing the following patches has been reported to solve the problem on Solaris 2.7: 107081-40 107656-07 For information (although they have not been confirmed to work), the equivalent patches for Solaris 2.8 are: 108940-33 108652-25 HTH, Vin
