After installing .952 I started up one of my files and noticed that the 4 Direction Behavior still has the same problem when you press two keys at the same time.
If you are walking up or down and you press the opposite key of the one that you are holding down your character stops moving and does their walking animation until you let go of one of the keys. This is fine.
If you press left or right while moving up or down nothing happens, you just keep going on your way.
However, if you are walking left or right and you press either up or down at the same time you moonwalk in that direction, rather than having nothing happen like when you are walking up or down. Note that if you are walking left or right and you press the opposite key your character does stop moving, like they should.
Sorry to bring this old problem up again...
