HAve run into intermittent problems logging in to an arena. All goes normally until entering the arena, when the map loads and roster freezes. The game itself looks normal, and the mouse works, but the roster will not populate and there is no text buffer data. The clipboard can move, but the map doesn't update either (radar circles, dot positions, etc.). Once entering this state, nothing can get it out -- and closing/reopening AH doesnt work consisitantly. Sometimes have had to reboot entirely.
