          Platform: All
        OS/Version: Windows 2000/XP

It seems that if you have Netmeeting's Remote Desktop Sharing running, OpenGL 
will fall back to software when in window mode, and GTK will misbehave.

Reproduction Instructions (Verified to work with NetMeeting version 3.01, 
copyright 1999):
 1. Run Netmeeting as Normal
 2. Select &Tools > &Remote Desktop Sharing...
 3. Complete Wizard as Appropriate
 4. Select &Call > Exit and &Activate Remote Desktop Sharing
 5. Run GTKr as normal

Possible fix: Detect if OpenGL wants to use a software renderer, and complain 
if it is. It might help with other software renderer related problems.
