Thanks GravityForce, but have been there done that. As I said, you can select ANY compatibility mode and try to run the game. But always, the game loads to the menu and you can only make a selections, e.g. to "Join Server" via moving the cursor with the tab or arrow keys. The mouse no longer works. So, when you get to the next screen to choose the server you want to join, there is no way to get down to that portion of the screen and select it manually. So, you can't even run the game to see if it will work in one of these compatibility modes. And, even if you could, not sure you could play anyway...if the mouse is disabled for some reason, can't really play the game.
