Hello all!
So you all say I should set windows desktop to the exact resolution/color the game is going to run with?
Yes? Is this right?
By the way, I did not managed to correct mouse behavior using the methods you suggested!

It is possible to play with such a mouse, but a bit annoying....
Well, one more fact: my mouse is connected to com port. Maybe I should use another mouse on ps/2 or even usb port? Can this be a problem?
