problems after compiz update

All, I am using FC6-test2 on Dell 700m with aiglx+compiz effects enabled. I updated compiz on FC6 test2 from compiz-0.0.13-0.23.20060817git.fc6.i386.rpm to compiz-0.0.13-0.27.20060817git.fc6.i386.rpm using yum and compiz went completely bonkers. Weird behavior included windows disappearing, being placed outside the visible area on the desktop, maximized windows appearing on alternate faces of the cube while using ctrl+shift+alt+rightarrow. The only way I could fix this was to revert to compiz-0.0.13-0.23.20060817git.fc6.i386.rpm. Have others experienced this problem ? if so, is there a way to fix this without reverting to the previous version ? Also, have anybody installed and used compiz-quinn, its plugins and cgwd with aiglx (NOT xgl) in FC6. thanks Ganesha
