Compiz seems to hurt my metacity.

[Naoki]

Probably a stupid problem and not a bug but..

Latest rawhide :

$ rpm -q compiz metacity
compiz-0.0.13-0.17.20060817git.fc6
metacity-2.15.34-1.fc6

When I try : System-->Prefs-->More Prefs-->Desktop Effects

It seems to remove all window management, I get all the applications 
from my eight workspaces on the one screen, I can no longer switch 
between workspaces (which has been reported before so I understand this 
issue) and the applications no longer have borders and are unable to be 
manipulated. 

Anybody else seen this or have I a bodgy setup?
