I've built an updated quartz-wm for Tiger (don't try using this on Leopard) for use with the new xorg-server in MacPorts. This quartz-wm will fix the "100% CPU issue when pasteboard proxying is enabled" issue and fixes the dock interaction bug that was present in the 1.0.0 version that I built a few weeks ago. This also brings Tiger users all the fixes that have gone into quartz-wm on Leopard (gravity hints, fullscreen hints, etc). http://static.macosforge.org/xquartz/downloads/quartz-wm-1.0.1-Tiger.bz2 download it, decompress it, and place it at /opt/local/bin/quartz-wm (or change /opt/local/bin to be your prefix). You will also need to 'sudo port -v upgrade xinit' to get xinitrc to use this quartz-wm instead of the system one. --Jeremy
