I'm creating a card game tutorial (well, a small part of what will be a tutorial) and ran into a wall.

A movieclip has an onRollOver, onRollOut, onPress and onRelease state, each doing different things (go figure). In the onRelease state, I nullified all 3 other states so that the movieclip becomes frozen, i.e. movieclip.onRollOver=null; etc.

How do I disarm the null when a reset button (resetBtn) is pressed?
