Help W/ MovieClip Mouse_Over Event

In the attached file, I have one movieclip with a MOUSE_OVER listener attached. On MOUSE_OVER, the movieclip should start playing @ frame 2 and stop @ frame 19. On MOUSE_OUT, the movieclip should start playing @ frame 20 and stop on frame 37.

For some reason, the MOUSE_OVER event keeps running as long the cursor is over the MC. Can’t seem to figure out why. If I remove the shape tweens inside the MC, the event seems to work fine.

Any suggestions are welcome.
