Camera Lock

I know others have posted about this already and its happened to me before but this time it was terrible. I couldn't get the screen to unlock until i exited the game and came back in. Have you guys had any leeway on this issue? Just a background of what happened. To try and fix my lag, i minimized my game window and dc'ed and reconnected my wifi ( Seems crazy, but it works sometimes ), when i got back in the game, everything was okay for about 10 seconds and then BOOM perma- screen lock.
