I've tried two different keyboards on my Mac Pro since 4.1 and with neither of them can I use ESC within WoW. It works outside of WoW, but not inside WoW. Not just in the toggle menu sense (that bind is set) but if I try to bind esc to something else, it doesn't sense the keypress, and if I am just at the deathwing screen (login screen) it still does nothing.
Any ideas? This is just since 4.1 as far as I can tell. it is driving me crazy.
