Since I'm not sure whether or not this is a mac specific problem or a general issue among everyone not including mac users I'm just going to be posting bug's in the mac forums and hopefully the right people will see them. Aaaanyways!

Last night I was trying to play some normal games, and after sitting there for a few minutes waiting queue I dropped out of the queue and played some practice games with some new decks I wanted to try.

During the middle of one of my practice games the screen went completely black and sent me into a normal queue game.

Thanks,

Jon.
