[MAC] Please FIX the hot/active corners on fullscreen, the game is barely playable since months !!!

I don't know exactly when but since the end of the last year the fullscreen mode doesn't work on mac. Active corners are triggered all the time and worst : right clicks, etc happen on your desktop behind the game's window. Which means you CAN'T even activate your spells in middle of the fights sometimes.

I'm not joking, every 2min I can't press my spells, so I spam "esc" button until it triggers the menu window so I know the game reads my inputs again.

This happens on Yosemite but I've read other older posts with many upvotes about newer versions of OSX.

So for the love of Faker or whoever you respect the most. PLEASE FIX THIS GAMEBREAKING and OLD BUG. Seriously !

Thank you !
