How to stop AS2 carousel from spinning when not moused over...

Question

Hello Adobe forums,
I've had a challenge that I cannot seem to figure out for the life of me right now.
I have set up a mockup spinning carousel on this page here using Actionscript 2:
http://iongeo.com/ru_innovation_test_dev/
What I would like however, is for the annimation to only be available when moused over on the .swf.   When the mouse is not placed inside the flash file, the animation would then stop.  Is this possible??
Any help would be greatly appreciated.
Thanks!
Here is the AS2 code that I have used for it:
import mx.utils.Delegate;
import mx.transitions.Tween;
import mx.transitions.easing.*;
var numOfItems:Number;
var radiusX:Number = 300;
var radiusY:Number = 75;
var centerX:Number = Stage.width / 2;
var centerY:Number = Stage.height / 2;
var speed:Number = 0.05;
var perspective:Number = 130;
var home:MovieClip = this;
theText._alpha = 0;
theHeader._alpha = 0;
var tooltip:MovieClip = this.attachMovie("tooltip","tooltip",10000);
tooltip._alpha = 0;
var xml:XML = new XML();
xml.ignoreWhite = true;
xml.onLoad = function()
    var nodes = this.firstChild.childNodes;
    numOfItems = nodes.length;
    for(var i=0;i<numOfItems;i++)
        var t = home.attachMovie("item","item"+i,i+1);
        t.angle = i * ((Math.PI*2)/numOfItems);
        t.onEnterFrame = mover;
        t.toolText = nodes[i].attributes.tooltip;
        t.content = nodes[i].attributes.content;
        t.header = nodes[i].attributes.header;

Answer 1

it's possible.  but, the main problem is detecting when the mouse is over your swf.
as2 doesn't have a good way to detect that.  there are many work-arounds but no matter which work-around you use, you'll set a boolean (say, mouseOverBool) to true when you detect the mouse is over your swf and set it to false when the mouse is not over your swf.  you can then use:
function mover()
if(mouseOverBool){
    this._x = Math.cos(this.angle) * radiusX + centerX;
    this._y = Math.sin(this.angle) * radiusY + centerY;
    var s = (this._y - perspective) /(centerY+radiusY-perspective);
    this._xscale = this._yscale = s*100;
    this.angle += this._parent.speed;
    this.swapDepths(Math.round(this._xscale) + 100);
// or to make this nicer, you can start a loop that decrements speed to 0 when the mouse is not over your swf.  and, as long as you're doing that, you may as well start a loop when you detect no mouse movement for some period of time that decrements speed to 0.  that will eliminate the need to check if the mouse is over your swf.
