Program works fine on my laptop. Error occurs on my desktop PC. Possible cause might be display configuration? Desktop has 2 monitors: Primary screen is 3840x1024 Matorx Triplehead. Secondary screen is 1920x1080 touchscreen in inverted landscape orientation, positioned centrally below primary. TOM is running on Primary display. However, problem DOES STILL OCCUR in 1024x768 Window mode.
If I run Visual Studio 2010 in the background (doing nothing - just sitting there), before starting TOM, then the error DOES NOT OCCUR - but I also have no cursor in the Mission Control screen - only in the menu screens if I press ESC!
So far I have found no workaround that makes the game usable on my desktop system!
