This looks interesting. Can you pleas file a bug report at xquartz.macosforge.org. It looks like it might be a libXplugin issue (so file a bug at bugreport.apple.com as well). Just judging by the top of the stacks, it looks like a deadlock in libXplugin.

Hi guys

I'm having problems with IDL 7.0 running under the new X11. Things have improved greatly with the recent upgrades, but X11.app freezes more or less randomly, as it did in X11 2.1.1. You can trigger this freeze if you resize a window 10-20 times.

Freeze details are below. (Not sure if this is relevant, but IDL seems to be Motif based - libXm.3.0.2.dylib). Everything works fine under the old X11. Any thoughts?

Cheers, Ricardo
