opengl demo crashes (Vista)

Hi,
I'm trying to run the teapot demo (and other opengl based demo's)

and i'm getting "Unhandled exception:Unhandled Memory Exception Error"

on gl commands (eg: flip in the teapot_test.bmx .. glxcube.bmx and glblurr.bmx just lock up and don't drop back to the program after the error)

I'm using Blitzmax 1.30 + maxgui on Vista with an ATI EAH3850 videocard and i have 4gb memory

Fixed.. updated my ati display drivers (from asus) from 8.5.1.1 to 8.5.2
now everything is working as expected.. sorry for troubling everyone
