I've read through 14 pages of the technical forum and looked at all the threads that had this problem and none of their resolutions can solve it for me, even the new full screen client. Literally nothing works, tried all permutations of options in the compatibility settings. edit: P.S this is for my friend - I've double checked it myself and it really doesnt work for anything.
change resolutions to 1480 x something and run as admin, also make the client run as windows 7 client instead of 8+
