OK…for anyone still having this problem. I use an iMAC desktop….1 year old…with 8gig RAM and a Logitech mouse and keyboard in place of the MAC issued ones. All I have to do is log-in normally, then hit escape and go to Support. As soon as the window loads, just close the window and re-open the game. Problem gone. I did say re-open….NOT re-start! It’s a pain, but it works properly from then until you actually exit the game.
Good luck to All!!!
