The infamous "pause" hack in Warcraft III has been around for quite some time. Even though Blizzard is trying their best at fixing it, many people are still victimized by this lethal hack. It pauses the game three times in the beginning, then all of your commands and graphics are "locked" on screen, meaning they stay there forever. You can't move your screen with your mouse, but you can move it with your keyboard; you can't drag a box around to select units, but you can click them individually; you can't right-click on items, but you can use your keyboard. I managed to beat someone with "pause" hack, and that made me smile.
