When you are in an area where the screen zooms in, such as the token trader or an elevator, or a crystal deposet box, your character will move to the bottom of the screen. However, your crusor will still react as if your character is in the middle, so even if I raise my mouse out in front of him, he will walk backwards. That being said, I prefer using WASD to move, so this generaly dosen't affect me, I just posted this for fact's sake.
