Hi Nick - that definitely narrows it down!

It basically means that MoI is not getting the expected information back from the video card.

Could you please try a couple of things?

First - can you please update to the latest drivers for your card here:

It may be some glitch in your particular video driver version - over here I have a machine with a GeForce 7350 LE which does not have the problem but I have a recent driver installed.


Another thing - can you please go to your video card control panel thing and look at the anti-aliasing settings and see if you have anti-aliasing turned on in the driver? If you do, can you please switch that to the "application controlled" setting and see if that also fixes the problem?

Thanks,
- Michael
