Is the platform Win32 or X11?
(I don't see this on w2k with CVS GLUI)

reply 2

I had the same problem running under WIN XP. Using a debug
version of the GLUI library, I have discovered that the
crash occurs in glui_special_func in glui.cpp

Looks like the value of glut_window->glut_special_CB is not
verified before it is invoked. I have invoked
set_glutSpecialFunc at start up but I passed a null to it.

I went ahead and prefixed all the calls to
glut_window->glut_xxx_CB in glui.cpp with checks for null
just to be on the safe side.
