Vista help ...

[Spud]

Guys ..

I know this hase been talked about before, but purchased a new computer yesterday which has Vista and - while CS Matrix works fine - I keep getting these big white patches over map when playing ...

I realize that I have to turn something off in Vista, but as am a computer ludite could someone please tell me "what I have to turn off" and - more importantly 'where it is" ...

Many thanks

Spud ...
