[Xquartz-dev] quartz-wm goes crazy on macbook air

[Christof Wolf]

Hi Jeremy,

I am on 2.6.1, xorg-server 1.9.5 and 10.6.7 - most of the time everything is 
normal, except just now quartz-wm went crazy - taking all cpu time - I had to 
kill it - no message on the console, not sure if the sample helps. It happens 
just once :-)

ciao
