I've tried two programs which use:
glutInitDisplayMode( GLUT_DOUBLE | GLUT_RGBA |
When calling glutCreateWindow, the inclusion of
GLUT_ALPHA above gives:
freeglut_window.c:300: fgOpenWindow: Assertion
`window->Window.VisualInfo != ((void *)0)' failed.
I've had this happen on my own program, as well
as on the nvidia cg_brush demo (from their website).
I'd be happy to give you any additional information
which might help.
