So after dealing with some network issues all day, and finally getting them fixed, my wow for some reason which was set to always run in windowed mode, started up in fullscreen, no problem, i tried to switch back to windowed mode. Now everytime i switch to windowed mode i get an error saying "The application encountered an unexpected error".
All my drivers are up to date, and everything worked JUST fine yeasterday. Anyone got any answer on why this is happening?
