Bug#432802: compiz: Compiz intereferes with workspace switcher and window selector applets

["Lapse of Reason" <lapseofreason0@gmail.com>]

I think your original problem might be related to
http://www.compiz.org/Workspace_Switcher_Fix as I was experiencing
similar problems.

It is not a particularly elegant fix, but the second part did the
trick for me: I set /apps/metacity/general/num_workspaces to "1" and
left my settings in /apps/compiz/general/screen0/options/ at their
defaults.

This means that I have set number_of_desktops in
/apps/compiz/general/screen0/options/ to "1" (looks like this should
always be the same as /apps/metacity/general/num_workspaces) and hsize
to "4", which gives me 4 virtual desktops (that all stay on the same
cube).

Hope this helps and that this gets fixed in future versions, because
it is strange that it is necessary to change metacity's settings to
fix compiz.
