Can't close Yast apllications after update to 11.3

Recently i’ve updated openSuse to version 11.3. But i’m experiencing strange behavior of Yast applications (y2base binary). I can open them but can’t close. For instance i’m trying to close “Software management” application after packages installation but it seems that its parent restarts it immediately after i close it. Of course i can kill y2base process but its a bit annoying. Please advise.

Anybody can help?

Try reinstalling yast.

Didn’t helped me at all. Anyway thanks for suggestion.
I tried to find a solution myself but no luck. Can anybody point me to bugtracker or similar of yast developers?
