is it possible to tell compiz to ignore certain windows

[Chris Jones]

Hi,

When running compiz under kde, compiz does not seem to distinguish 
between "normal" windows and the kde panels. It includes them in the "view 
all windows" and "list windows" features, which is kind of annoying, and 
sometimes causes them to vanish.

Is it possible to tell compiz to ignore these windows ? Or is there some other 
way to work around this ?

cheers Chris
