AS3 Tween not finishing

All

I have a problem that I have read a few other threads about, but the solutions that are offered don’t seem to work for me.

The solution offered was to declare the tween variables outside the function…

I have done this, but every now and then it doesn’t finish the tween.

Here is my code for that part…Any Ideas!!!

var alphaTween:Tween;
var myTimer:Timer=new Timer(150,0);

myTimer.start();
myTimer.addEventListener(TimerEvent.TIMER, addMC);
    
function addMC(event:TimerEvent):void {

    var mc:MovieClip = new mClip();
    loadArea.addChildAt(mc,1);
    mc.mouseChildren=false;
    mc.mouseEnabled=false;

    mc.gotoAndStop(Math.ceil(Math.random()*6));
    mc.x=Math.random()*loadArea.width*0.9;
    mc.y=Math.random()*loadArea.height*0.9;
    mc.width=mc.width*Math.random()*1.5;
    mc.scaleY=mc.scaleX;
    mc.rotation=Math.random()+1*360;

    alphaTween = new Tween(mc,"alpha",None.easeNone,1,0,1,true);
    alphaTween.addEventListener(TweenEvent.MOTION_FINISH, fadeOut);
    function fadeOut(event:TweenEvent):void {
        if(loadArea.contains(mc)){
           loadArea.removeChild(mc);
           }
    }

}
