Black screen when you minimize the game and bring it up again.

I used Alt+Tab to close a google chrome window during a game to bring my ping down and then it black screened and it still played the sounds but would not let me... Turn off my computer. Alt+Tab back out. Control alt delete out.

But I could still listen to the sounds coming from the game.

I unplugged my computer and turned it back on only to find it will not open. Only give me a message saying it's already running.

Edit: I got leaver warning while buying items in the shop so I guess this is a 2 glitches in one post special.
