MIT X Applications under 4.1

[Gordon Jacobs]

I just upgraded to Ultrix 4.1 on a DECstation 3100 and
I run the mwm window manager (or twm sometimes). I have
changed my login window to be an xterm by modifying the ttys file.
I notice that for some of the MIT applications in /usr/bin/X11,
when they are closed with the "Close" entry on my window menu (to
quit the application), I get an endless stream of Error messages
from the Server related to XKillClient.  The application does not
die until I manually kill it from another window.  This is particularly
a problem when I run a script from my login window to start the
window manager and all of my xterms.  When I log out, the error
messages never end (unless I rlogin from another machine and kill all
of the hung applications)

Is this a known server problem and are there any solutions?
Thanks a lot,
Gordie Jacobs
