follow mouse with constraints?

[ripple]

I have a MC with an object that follows the mouse. But is there anyway to do this within a specific area WITHOUT using a button?
(similar to this tutorial: http://www.actionscripts.org/showMovie.php?id=270
but without the button?

You can use a MC

onClipEvent (enterFrame) {
if (this.hitTest(_root._xmouse, _root._ymouse, true)) {
some_action_1;
} else {
some_action_2;
}
}

That's it. Thank you.
