Hi, just for the sake of it I've installed alpha2 - same effect, the CPU goes crazy up to 100% :-( I did two tests - with no difference - but maybe it helps to figure out why that happens 1) xinitrc reads like this (plus all options of "enable syncing" are on) . /sw/bin/init.sh export KDEWM=quartz-wm quartz-wm --only-proxy & /sw/bin/startkde>/tmp/kde.log 2>&1 see console file www.loyolaproductions.com/munich/console.txt see sample of the process www.loyolaproductions.com/munich/sample_of_x11.txt 2) xinitrc reads like this and I disabled all "Pasteboard" options in the X11 preferences . /sw/bin/init.sh #export KDEWM=quartz-wm #quartz-wm --only-proxy & /sw/bin/startkde>/tmp/kde.log 2>&1 see console file www.loyolaproductions.com/munich/console_no_pasteboard.txt see sample of the process www.loyolaproductions.com/munich/sample_of_x11_no_pasteboard.txt any idea? - I am back to 2.3.2_beta1 :-) 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.
