Now select the folder of the game with which you have problems, open it, right click on the game icon and go to "properties".
Now go to "compatibility" and check the "disable full screen optimization" box. Click ok.
Voilà! Problem solved! I had two other games with this very same bug, and fortunately this solution worked for all of them, ^_^ .
