Movie Clip BUttons

Hello!
I was wondering how to make a complicated button. :slight_smile:
There are some good examples on the kill bill website www.kill-bill.com

basically I’m trying to find out how to make a button that when you mouse over it, it animates, and when you mouse out, it animates it backwards.

I can do it basically, but a feature on the killbill website i would like to learn is that when you mouse out (even in the middle of playing it) it reverses to close it. - kinda cool.

anyway, if anyone knows how to do it or where i can find out how that would be really awesome, thanks!
