After joining a room (and in the beginning of gameplay) the game just becomes unresponsive
i.e. can't move, shoot, check player stat (tab) for the GAMEPLAY time.
Then afterwards, at the screen where the gold and xp and rankings for the game is shown (when one side wins/loses), I am able to click "Exit" (or whatever it is), and in the lobby, "Ready" or "Start Game." In other words, I regain "control"
When this happens, I usually just alt+tab out and close the game window and start the game up again. But it really sucks
