I have recently added a second monitor to a friends computer and it is working fine, except that it says that I have got three screens and the main screen it says is two.
The below screenshot will clarify more:

The problem is that when I go into a game (or other fullscreen programs) it will change the order of the screens, so screen #1 will be on the left after I come out of a game.
Please let me know if you can think of anyway of changing/stopping this.
