Problem with Mc Button

Okay so, I’m not exactly sure what i’m trying to do but I’m creating a main screen for a game. The game is going to be something like, don’t get hit be large meteors heading toward you in the middle. Right now with the main page before you press play, I have three mc buttons that I have created, I thought it worked well until I started to mess around with it and I moved back and fourth over the button very fast. When I did so, the mc decided to get stuck at the “over” state and when I scroll over it goes back to the “notover” state. The answer is probably extremely simple but I am completely tired/sleepy/hasnt had my coffee.:snooze: I have attached my swf and fla.
Thanks,
