What title says, game loads and credits start, it minimizes but keeps playing, i go back into the game and make it to main menu but it keeps alt tabbing litteraly every second, making gameplay impossible.
I had the same problem in Win 7. I solved it by right clicking on the shortcut that starts the game (I use a desktop one), select properties, go to the tab "compability" and check the boxes "Disable visual themes" and "Disable desktop composition". This makes Win 7 turn off some graphic gimicks while the game is running, and re-enable them when the game ends.
I hope that helps.
Whoa, it switched the original posters' names with ours. Weird.
