Using Multiple Event Listeners

Question

Hi,
I have a movielcip (A) class in which I have used a Tween class effect on a child movieclip (B) scrollRect. The (B) Movieclip in turn has several movieclips whose have tween class effect being executed on thier child movieclips.
the tweens are all unique to each movieclip
and the event listeners are taken off once completed.
This works all well and good in FLASH IDE...
My problem arises when I try to view this in a browser on a Windows XP
it doesnt work in
Opera Version 9.63
Firefox 2.0
and Google Chrome 2.0
The only browser it works fluently in is
Internet Explorer 7.0.5
What is happening in most cases it that the animation appears to "stick" but i think what may be happening is the listening or removal of the event listeners. The animations are left incompleted.
Is there any rule of thumb when using multiple event listeners?
here is a snippet of some of my code
on click event from movieclip (A)
private function scrollToSlidePrev(e:MouseEvent) {
               if (((slideIndex - 1) >= 0)) {
                    nextButton.mouseEnabled = nextButton.enabled = previousButton.enabled = previousButton.mouseEnabled = false;
                    var position:Number = 0-SLIDEAREA.width;
                    var slide1:TileListSlide = slides[slideIndex] as TileListSlide;
                    var slide2:TileListSlide = slides[--slideIndex] as TileListSlide;
                    scrollSlide(position,slide1,slide2);
tween animation in movieclip (A) on (B)
private function scrollSlide(pos:int,slide1:TileListSlide,slide2:TileListSlide) {
               slide1.resizeSlideTo(0.6); // execute tween on child movie clips in B
               slide2.resizeSlideTo(1); // same as above;
               var rect:Rectangle = sliderMc.scrollRect;
               var tween1:Tween = new Tween(rect,"x",Regular.easeOut,rect.x,rect.x + pos,3,true);
               tween1.addEventListener(TweenEvent.MOTION_CHANGE,setSliderScroll,false,4);
               tween1.addEventListener(TweenEvent.MOTION_FINISH,toggleButtonEnabled,false,3);
tween animation in movieclip (B) children
public function resizeSlideTo(sc) {
               var m:Matrix = tileList.transform.matrix as Matrix;
               var p:Point = new Point (m.a, 0);
               var tween2:Tween = new Tween(p,"x",Regular.easeOut,p.x,sc,3,true);
               if (numericStepper != null) {
                    if (sc != 1) {
                         numericStepper.visible = false;
                         tween2.removeEventListener(TweenEvent.MOTION_FINISH,showStepper);
                    if (sc === 1) {
                         tween2.addEventListener(TweenEvent.MOTION_FINISH,showStepper,false,2);
               tween2.addEventListener(TweenEvent.MOTION_CHANGE,setScaleOnScroll,false,3);

the effect disables and re-enables the buttons when its done.... then the listeners are removed.
each one with the exception cretes its own unique tween (obviously this is a custom class built as each clip)
i really don't know what to make of it guys         

Answer 1

apparantly making the tween a property of the class rather than a random variable in a function worked.....go figure
