Here is how I did it. This is from openspeedway.net
Running the game in a Window - Running the game in a window let's you jump back and forth to your desktop without getting of the of game.
1. First, you have to run the game at the same resolution as your desk top.
2. Run the 3D config and check the "Run in a window" box.
3. Go into your game folder using Windows Explorer and find the app.ini file.
4. Open the file and look for the 2 lines like this:
windowTopLeftX=0
windowTopLeftY=0
5. Change the "windowTopLeftX=0" to windowTopLeftX=-3
6. Change the "windowTopLeftY=0" to windowTopLeftY=-23
7. Start the game, you only want to see a small line at the top of the screen. You don't want to be able to see the boxes to minimize the screen, but you should still be able to find them.
8. To raise the window higher, raise the "windowTopLeftY=" number.
