Game not running with dual screen setup

[Semple]

I'm really stumped by this but i installed Sim City 4 a fairly old game. Anyway i have two monitors in a dual set up. When i click to run the game both screens flash for a second or two and then my desktop appears again as if the program got minimised. No matter what i've tried to do the game just wouldn't open out.

Anyway i figured i'd disable one screen and try it on a single monitor. This worked perfectly.

Does anyone have any tips how i could run this game without having to disable my second monitor everytime i want to play the game.

Cheers

Ah i may just give that a try, as mine is setup differently. Main screen on the left and secondary on the right.
