I think I've fixed the major issues that were still present in 2.3.2- rc4. I've uploaded a drop-in binary for testing... If you're not comfortable with this process, just wait for the final package release. The following issues should be addressed: 1) Root window shows a strip of the OSX desktop at the bottom the first time it's used * This caused a crash if you'd do something like 'xsetroot ...' in that state 2) Fixed a deadlock issue between our pbproxy/appkit/server threads 3) Run applications using '/bin/sh -c' (or whatever your login_shell default is set to instead of /bin/sh) 4) Don't pass a character to the X clients when doing cmd-alt-a to enter/leave fullscreen (This has no impact on the shell script issues that are being discussed) Instructions: curl -LO http://static.macosforge.org/xquartz/downloads/X11.bin-1.4.2-apple29.bz2 bunzip2 X11.bin-1.4.2-apple29.bz2 sudo cp X11.bin-1.4.2-apple29 /Applications/Utilities/X11.app/Contents/ MacOS/X11.bin sudo chmod 755 /Applications/Utilities/X11.app/Contents/MacOS/X11.bin
