    [COLOR=#0000ff]  private function onMenuItemClick(event:MouseEvent ):void {
            lastMoviePlaying.load(new URLRequest(images[lastMoveIndex][email protected]));
            for (var i:int = 0; i < circleMenu.numChildren; i++) {
                circleMenu.getChildAt(i).removeEventListener( MouseEvent.CLICK, onMenuItemClick );
            }
            circleMenu.scrollToItem(event.currentTarget as DisplayObject);
            lastMoviePlaying = event.target;
            lastMoveIndex = event.target.name;
            setTimeout(LoadMovieClip,250,event.target,(images[event.target.name][email protected]));
        }
        private function LoadMovieClip(ldr:Loader, movieName:String):void {
            if (movieName !=null && ldr != null) {
                ldr.load(new URLRequest(movieName));
            }
            for (var i:int = 0; i < circleMenu.numChildren; i++) {
                circleMenu.getChildAt(i).addEventListener( MouseEvent.CLICK, onMenuItemClick );
