Well... I don't know what to say. I got it again after checking out the svn MaxGUI source, rebuilding modules, and now trying the GTK module on top of that again. The exact error message is:
This is dying on the call to WaitEvent(). I have made minor control position changes - nothing that should make a difference in this behavior.
Unhandled Exception:appstub.linux signal handler 11
