[Bug-gnubg] gnubg hangs when closing Appearance prefs on MacOS X

[Olivier Baur]

Hi all.

On MacOS X 10.3, when I close the Appearance prefs, gnubg hangs, in 
gtk_gl_widget_destroy_gl_context.
Any idea, someone?

BTW, the 3D board preview now properly displays in the Appearance prefs 
window (not upside down anymore)
