[compiz] kde 4.3 beta 2, compiz 8.2 - panel pager doesn't work until plasma crash and restart

[Adam K Kirchhoff]

KDE (3 or 4) has never properly supported switching between window 
managers in a running session (*).  There is an option in systemsettings 
to switch the default window manager, and if you select compiz, it will 
start up compiz before plasma, and, as as result, the pager will work 
properly once it starts up.

(*) Newer versions of KDE4 will switch window managers, on the fly, when 
you change it in systemsettings and, at least for me, I do not have the 
pager problems any more if I switch to compiz from kwin that way.
