Actually I had already put a note about this in the pl36 BUGS file.
Destroy should NEVER be used to close an application unless Close
doesn't work. From the fvwm man page:
Destroy
Destroys an application window, which usually causes
the application to crash and burn.
This is because it uses a very brute force method for closing the
window. It should especially not be used on the Buttons module, since
then the Buttons module cannot close it's swallowed windows correctly.
Pl 36 has fixes so FvwmButtons kills it's swallowed children more
cleanly more often now, but I haven't found a way to catch the Destroy
action yet.
I was thinking about modifying Destroy to try a Close action first,
and then the more brute force method if that didn't work. Perhaps
I'll investigate this a little more...
