Minimized windows disappear in FC3

[Tom Eastgard]

All -

Strange problem with FC3 install that I haven't seen mentioned on the 
list:  Whenever I minimize a window, it disappears. There's not the 
usual box/icon/whatever in the panel that one would normally click on to 
  restore said window.

The process continues to run, but I have to start another instance of 
hte app to get it back up on my desktop.  Needless to say, work is not 
saved.

Wondering if there's a config parm somewhere that I've missed...?

Ideas?

TIA,
