Compiz windows decoration and other plugin problems

Hi,
OSS11.4
KDE 4.6.00 (4.6.0) “release 6”
Compiz 0.9.2.1.5.5 (standard OS repo)

got compiz window decorations to work with no big problems with command

kde4-window-decorator --replace

But the problem is that it does not work properly afterwards.
Title bar bottoms are ‘frozen’ (close minimize/maximize don’t work). Windows switch Plugin (with toolbox kit plugin)
kills my title bar, task bar and leave me with no responding keyboard, so i have only mouse to close windows and re-login to have everything back. Have you any idea what could be the problem?

Cheers

P.S. with no intentions to be rude, please do not suggest installing emerald or use Kwin instead.
