AS3 menu help

Hi all,

I have a simple menu with 4 buttons. When I roll-over the button with my mouse it plays an animation (for example a shadow effect). How can I do that, if I click on that button and I'm on that actual page it shows me that animation (the shadow) continuously even if I roll-out my mouse.:confused:

Thanks

The idea would be to change the event handler that affects the animation. Instead of the mouse making it work, it would probably be onenterframe or something like that.
