Flash 8. Actionscript 2.0

I made a movieclip with scrolling images that are buttons with links, It loops continuously. All I need is to make it stop/pause when I mouseover it. I tried this.stop and hittest etc but it stops forever and does not move afterwards. Your help would be appreciated. Thank you

Here is the script I made

onClipEvent(load){
scroll = +3;

myClip.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;
	   
	   
 }

}

}

onClipEvent(enterFrame){
_x -= scroll;
if (_x > 0) _x=-5051.1;
if (_x < -5051.1) _x=0;

}
