i've just installed Warcraft III: Frozen Throne and it runs flawlessly out of the box

the only problem is i have to disable my second monitor for the game to sit properly on a single screen...
can anyone tell me how can i setup the video for this game or on my pc so i can run both screens and the game to run on one screen?
or how can i run the game not on full screen?
