Help! GLMame32 only displays white screen!

[Indiana]

Hello,
Anybody tried the OpenGL port of Mame?
I can't get it to actually display anything other than a white window in OpenGL mode on my G400. The games are working as you can hear the sound, it's just that you don't see anything of it - as said just a white screen.
If you turn off OGL and use DirectDraw everything works correctly.
All the other OpenGL-progs I've tried so far (QI-III, Tirtanium, some screensavers) work without problems.

I used PD5.52 with the newest OGL ICD.
I have a G400/16MB DH on a Asus K7M (latest bios 1008) with a Athlon600 if that matters.

Hmm, I can't believe noone here is old enough to know and appreciate those great old games like Gyruss, Ghosts'n'Goblins, Commando,...
And I'm sure they would look better with the OGL-version, but it just displays a white window/screen.
Anyone has a solution or at least any idea what might cause this?
