Horizontal Sliding Menu - constraining onRollOver action

I have borrowed a sliding horizontal thumbnail script I found online and have successfully gotten it to work. The only problem is that I would like to either stop the action or ease it down when the mouse is out of the menu area. My sliding menu clip will be called into a level on another file, so I don't want the mouse action to work unless it is only in that MC area. Is there an easy way to do this? I'm willing to use a completely different script if there is a better one, but this one has the general behavior I want (i.e. the menu needs to loop, I want the action to accelerate on the perimeters, the sliding motion should be smooth, and I need to be able to have button actions on the menu). here's the script I have right now:

code:

---

panel.onRollOver = panelOver;



function panelOver() {

	this.onEnterFrame = scrollPanel;

	delete this.onRollOver;

}



var b = stroke.getBounds(_root);



function scrollPanel() {

	if(_xmouse<b.xMin || _xmouse>b.xMax || _ymouse<b.yMin || _ymouse>b.yMax) {

		this.onRollOver = panelOver;

		delete this.onEnterFrame;

	}

	

	if(panel._x >= -121) {

		panel._x = -1825;

	}

	

	if(panel._x <= -1847) {

		panel._x = -140;

	}

	

	var xdist = _xmouse - 250;

	

	panel._x += Math.round(-xdist / 10);

}
