When I wanted to enter the game it froze when I Alt+Tabbed out of the game so much, that the music lingered and the cursor stayed, doing absolutely nothing. Ctrl+Alt+Delete couldn't solve it either. I could click Task Manager, however the cursor was so persistent, that it didn't allow me to click Anything. Windows key let me to Log Out but this is too much! What if I had something unsaved? Please fix it, if you have the time. Thank you so much, yours sincerely,

Sorry for adding it twice, you can delete whichever you want to.

Can't say I've experienced this issue. Perhaps it's your hardware?
