George has put some extra work into GLX that I'd like to put out into the wild. You need to install 2.3.2_beta1 first, then update the X11 binary to 1.4.2-apple19 from here: http://static.macosforge.org/xquartz/downloads/X11-1.4.2-apple19.bz2 Just download, decompress, and replace /Applications/Utilities/X11.app/ Contents/MacOS/X11 with it. Thanks, Jeremy
