In recent versions Sawfish changed its handling of "unmapped" windows: It
ignores them completely, you cannot even get-window-by-id them.

Indeed, once the window is unmapped (and I/we suspect it's Sawfish to unmap them
somehow), there is "nobody" why tries to remap them back (you might probably write
a utility to do it, though).


So, somebody should find a bug in Sawfish, where it unmaps a client window and
thinks that it was the client who requested the unmap. I once tried to see, if
window ID recycling could cause problems but I didn't finish it.


So, you should read src/events.c and think about all (time) possibilities...


I wish I could recommend you my modification of sawfish ...

... but it's currently half-done revision of many parts. I currently work
on removing flicker(ing) in some types of applications, so I don't hurry
finishing my sawfish experiments.
