Alt-F4 HOTKEY BUG

Vean y lean, y además viniendo de un forero nivel 80. El WoW ya no es lo que era, qué pena…

Ok im new to hotkeying so im most likely doing something wrong.

I can hotkey alt to anything but the function keys. I can do alt+f1, f2, f3 but when i get to f4 it crashes my game EVERY TIME! Its annoying because I have to reset all my hotkeys cuz a game crash doesnt save them. Please fix soon!
