simple-ccsm enabled, problems minimizing, closing windows

Hi,

i’ve installed opensuse 11. after that, i followed the article on wiki on how to 1-click install latest nvidia drivers, which went as charm- no problems at all. Then, i enabled desktop effects through command “simple-ccsm &”. No crashes whatsoever-

what is bothering me is, when i try to minimize some window, i’m clicking the minimize button, but nothing happens. so after few fast click- it finally minimizes or closes.

it doesn’t matter if the window is maximized or not… but is really irritating me.

help me out how to solve this please!

thank you.
