thanks for your replies, been caught up with work and recently just remembered to check the topic again :S
well i tried changing my resolution to what was suggested, but still not luck.
i tried changing the compatibility mode, but when i open the game steam says cant do it, turn off compatibility mode. (sigh)
minimising and maximising didnt work as well
im thinking of running it in windowed mode but not sure, any one know how to?
any other suggestions would be greatful
