This MG bug is more general, you can also get it while playing video poker. But it is rare.
It happens when you press the 'stats' or 'options' when playing
VP or slots, but it is not reproducable. What can happen is that the pop-up window gets stuck behind the main game window and you can not get it back into focus by any means. And you can not do anything on the main game window until you can closed this pop-up window. I have to kill the casino from the taskmanager and then reload the casino. Alt-tabbing to other programs also seems to can cause this to happen. Am I the only one who seems to suffer from this bug?
