I have some spaces-related fixes that I'd like some of you to try. I don't want to include this in 2.3.1 this late into the release cycle, so this is probably going to find its way into 2.3.2 beta to make sure there's no adverse effects I don't notice... in any event, here's how to get the updates: Start with 2.3.1_rc5, then replace libXplugin.1.dylib with a decompressed: http://people.freedesktop.org/~jeremyhu/PR-5880329/libXplugin.1.dylib.bz2 And /usr/bin/quartz-wm with a decompressed: http://people.freedesktop.org/~jeremyhu/PR-5880329/quartz-wm.bz2 mkdir PR-5880329 cd PR-5880329 wget http://people.freedesktop.org/~jeremyhu/PR-5880329/libXplugin.1.dylib.bz2 wget http://people.freedesktop.org/~jeremyhu/PR-5880329/quartz-wm.bz2 bunzip2 libXplugin.1.dylib.bz2 bunzip2 quartz-wm.bz2 sudo cp libXplugin.1.dylib /usr/lib sudo cp quartz-wm /usr/bin ---- This should address some parenting issues. Open windows not moving spaces with their parent, etc. I know that the xemacs menus appearing in the original space issue is still there, but I'm more concerned about testing for possible regressions. Let me know if you come across any or your feelings about how this compares with the current experience with X11 and spaces. Thanks, Jeremy
