Microsoft has purposefully planted a bug in the popular MMORPG “World of Warcraft”. This seems to affect all Windows-based computers, though the entire span of this bug has yet to be determined. Adept player Kwakmeister reported the bug in Warcraft forums late last night.
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!
This does not seem to be an issue with the Warcraft code itself; rather, it seems that the popular OS company Microsoft may be to blame.
The Alt + F4 hotkey can be critical in gaming situations, so it seems that someone is to blame. It is not yet clear if this was an issue surrounding the controversial Windows Vista operating system, or if it was an intentional oversight by Blizzard.
Responding to the hostile accusation was Blizzard’s own blue poster Maaven:

Alt+F4 closes out the current window on all windows based programs. It’s not a bug, glitch, or on purpose. If you don’t believe me right click a window bubble at the bottom of the screen. It will read Close Alt+F4. It’s always funny and frustrating to read anything related to this “problem”. I hope people stop thinking Blizzard is behind this sinister plot to close out peoples windows.
