Problem with Drawing

[S. P. Gardebiter]

A friend of mine just tested my game
In window mode the window pops up but the screen is white.
My friend is using Windows Vista...
My game is running well on my PC and on another PC too
As far as I know my friend has got the OpenGL drivers.

Strange. I'm on Vista, too. It should work.
Upload a minimal demo, please (with source)

[S. P. Gardebiter]

My whole game is actually some kind of minimal demo where only the biggest part of the engine is completed
So sorry...
Anyway

Gameflow is for spawning enemies.
Collision explains itself, as well as Player and Enemy.
EBullet are actually the enemy bullets. Music does nothing yet.
Frames draws the frames and Background is for the 3D background.

EDIT: Whoops, forget the link XD

runs perfectly on Vista. Must be his drivers. Is it the NVidia bug again? Try turning "Threaded Optimization" off.
