Ah... hmm... yes, try disabling KDE and just using quartz-wm.  Does it   work in that case?

Jeremy, I disabled KDE it worked immediately :-) then I opened the KDE control center and changed the rate from 25 to 11.3 (I remember you had something like this set on your system) - and that solved the problem. Weird?! it should do it with 25 too, however everything works :-) ciao christof -- public key www.hfph.mwn.de/~chwolf/chwolf.asc Please respect my privacy and do not make my contact information available to third parties.
