The second guy is absolutely wrong because unless you have steam which does not work on my computer for some reason even on full screen if you accidentally click on the top or the side it will yes please your screen and kill your character essentially ruining the game and discouraging people from wanting to play above level 80

Even on full screen by clicking the top or the side it will freeze your screen for at least 5 seconds
