ok, that's a very minor thing but... but I'll let you know.
The problem is the following.
I use W.Maker as coming from RH 5.2 (I think it's simply
great!). Everityng works just fine, but if I use the
Exit->Restart menu command more than once in a session,
instead of restarting itself it switch to some other WM
(usually "blackbox" if it is installed, or fvwm if not) or,
more rarely, it just quit the session.
We were unable to replicate this on test machine in our lab.
