GTA problem! :)

Well I see many here are playing SA online, and I'd like to give it a shot.

I've SA on my pc, but like two monthes ago I had a problem there which stopped me from playing.

I can't use my mouse during the game itself, I mean, on the options menu, it works compeletly fine (I can browse between the options with the mouse), but in the game itself, the mouse doesn't react (Can't shoot or aim)


Any ideas? :(
