The Error Report Pop-up is a misleading trap that appears in The Guy's Fortress, specifically the room with Ryu Hayabusa's portrait. It makes the user believe that his or her game has crashed, but it is just a trap to confuse him or her. The Kid will not be able to move when it first appears, until it falls down, giving the player just enough time to move out of the way before it kills The Kid. This trick only works once, as any subsequent playthrough, the player should realize the trap. The pop-up also seems to be a Windows XP pop-up, so if the player has a different operating system, such as Windows Vista or Windows 7, the player may easily tell that the pop-up is fake.
