Transition_Manager and unloading external swf problems

Question

Hi there
I´m having a few problems with my project which i although it work it has some unpleasant bugs that i´m trying to solve for days.
When i load external swf´s they show up on top of the Menu button.Maybe because the button i´m pressing is inside the same movieclip as the Menu.
Explaining better here´s a little diagram of my site:
con2 MC (Instance of Menu) ---> cont3 MC (Instance of subMenu) and mainButton MC (Instance of Main)
Here´s the general code which is inside the Painel.as
package {
    import com.greensock.TweenLite;
    import com.greensock.TweenMax;
    import com.greensock.*;
    import com.greensock.easing.*;
    import flash.display.*;
    import flash.events.*;
    import flash.display.MovieClip;
    import fl.transitions.*;
    import fl.transitions.easing.*;
    import flash.net.URLRequest;
    import flash.display.Loader;
    import flash.events.Event;
    import flash.events.ProgressEvent;
    public class Painel3 extends MovieClip
        private var inFocus:MovieClip;
        public function Painel3():void
            setupClips();
            addEventListener(Event.ENTER_FRAME, loop);
        private function setupClips():void
        con2.mainButton.addEventListener(MouseEvent.ROLL_OVER, onOver);
        con2.mainButton.addEventListener(MouseEvent.ROLL_OUT, onOut);
        con2.mainButton.addEventListener(MouseEvent.CLICK, onClick);
            var len:int = con2.cont3.numChildren;
            for(var i:int=0; i<len; i++)
                var mc:MovieClip = MovieClip(con2.cont3.getChildAt(i));
                mc.buttonMode = true;
                mc.loc = [mc.x, mc.y];
                mc.addEventListener(MouseEvent.CLICK, onClick);
                con2.cont3.visible = false;
        private function onOver(e:MouseEvent):void
        private function onOut(e:MouseEvent):void
        private function onClick(e:MouseEvent):void
            con2.cont3.visible = true;
TransitionManager.start(con2.cont3, {type:Wipe, direction:Transition.IN, duration:1, easing:None.easeNone, startPoint:5} );                       
        private function loop(e:Event):void
            var distx:Number = mouseX / 1400;
            var disty:Number = mouseY / 1400;
            TweenLite.to(con2, 2, {
                        rotationY:(-70 +(145*distx)),
                        rotationX:(70 -(145*disty)),
                        ease:Expo.easeOut
And then inside the subMenu.as class for the movieclip subMenu i have the buttons that load the external swf´s:
package  {
    import com.greensock.TweenLite;
    import com.greensock.TweenMax;
    import com.greensock.*;
    import com.greensock.easing.*;
    import flash.display.*;
    import flash.events.*;
    import flash.display.MovieClip;
    import flash.net.URLRequest;
    import flash.display.Loader;
    import flash.events.Event;
    import flash.events.ProgressEvent;
    import fl.transitions.*;
    import fl.transitions.easing.*;
    public class subMenu extends MovieClip {
        public function subMenu() {
            // constructor code
            menu1.buttonMode = true;
            menu2.buttonMode = true;
            menu3.buttonMode = true;
            menu4.buttonMode = true;
             menu1.addEventListener(MouseEvent.CLICK,link1);
             menu2.addEventListener(MouseEvent.CLICK,link2);
             menu3.addEventListener(MouseEvent.CLICK,link3);
             menu4.addEventListener(MouseEvent.CLICK,link4);
        function link1(e:MouseEvent) {
           function startLoad()
            var mLoader:Loader = new Loader();
            var mRequest:URLRequest = new URLRequest("AugmentedReality_v1.swf");
            mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
            mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
            mLoader.load(mRequest);
function onCompleteHandler(e:Event):void {
var swf:DisplayObject = e.target.content;
swf.x = -400;    
swf.y = -300;    
addChild(swf);
function onProgressHandler(mProgress:ProgressEvent)
       var percent:Number = mProgress.bytesLoaded/mProgress.bytesTotal;
       trace(percent);
startLoad();
        function link2(e:MouseEvent) {
            function startLoad()
            var mLoader:Loader = new Loader();
            var mRequest:URLRequest = new URLRequest("Fotos.swf");
            mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
            mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
            mLoader.load(mRequest);
function onCompleteHandler(e:Event):void {
var swf:DisplayObject = e.target.content;
swf.x = -400;    
swf.y = -300;    
addChild(swf);
function onProgressHandler(mProgress:ProgressEvent)
       var percent:Number = mProgress.bytesLoaded/mProgress.bytesTotal;
       trace(percent);
startLoad();
        function link3(e:MouseEvent) {
        function link4(e:MouseEvent){
            function startLoad()
            var mLoader:Loader = new Loader();
            var mRequest:URLRequest = new URLRequest("Texto.swf");
            mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
            mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
            mLoader.load(mRequest);
function onCompleteHandler(e:Event):void {
var swf:DisplayObject = e.target.content;
swf.x = -400;    
swf.y = -300;    
addChild(swf);
function onProgressHandler(mProgress:ProgressEvent)
       var percent:Number = mProgress.bytesLoaded/mProgress.bytesTotal;
       trace(percent);
startLoad();
Like i said the swf´s show up on top of the Menu and i need it to dissapear.
Also i want to unload the swf currently in scene so that when i load another one they don´t pile on top of each other.
Pls help. Thanks

Answer 1

Oh btw, i´m having an error 1069 Property TransitionManager not found in subMenu and there is no default value
at fl.transitions::TransitionManager$/start()
    at Painel3/onClick()
This doesn´t happen when i uncheck the Export for actionscript in the subMenu class but i can´t do that or else the buttons wont work.
