Adding Thumbnails Tutorial

I have no issues with the tutorial at all. In fact, I love it! What i’m trying to figure out now is how to disable the scroller when the mouse is out of the area. I was trying to build on the code below by trying to add a new function to disable the scroller but I can’t seen to make it work. Can anyone help out?? Thanks :esmirk:

panel.onRollOver = panelOver;
function panelOver () {
 this.onEnterFrame = scrollPanel;
 delete this.onRollOver;
var b = stroke.getBounds(_parent);
function scrollPanel() {
 if(_xmouse<b.xMin || _xmouse>b.xMax || _ymouse<b.yMin || _ymouse>b.yMax) {
  this.onRollOver = panelOver;
  delete this.onEnterFrame;
