Dear all,
I was using kde while all windows dissapeared. I think the problem is caused with the kwin
if for example I launch kwin and the kill it again... the lost windows appear again

(the virtual desktop is lost so all windows appear to the same "window")

please have a look in the screenshot here how the windows look like

ImageShack® - Online Photo and Video Hosting

my guess is that while I was working kwin crashed and the new one that started automatically just replaced the old ones..

How I can recover from this error? I can not afford a restart as I need the applications running.

I am running kde 4.7.2 (release 5) with 12.1 opensuse.

I would like to thank you in advance for your help
