I hadn't followed up on my earlier postings on this since I was
doing some testing (and have also been busy on the things I'm
paid for <grin>). It turns out that the problem with FvwmButtons
looping is more likely the fact that it was doing Xlib calls in
the signal handler, which is supposed to be illegal. I've changed
it to just set a flag, which would force exit from the main loop
and then do the cleaup, but it doesn't seem to work properly yet
(swallowed programs get left running on a restart).
Based on this, I suspect your problem may not be the signal handler.
What I suggest you do is break into the looping process(es) with your
debugger, get the call stack, and post it to the list. We can proceed
from there.
I'll post the change to FvwmButtons when I'm sure it works okay.
