[Flash CS3 AS2] External SWF Tween can't unload after loaded! HELP!

programming flash
1

Hi all,

I have a gallery with tween effect which allows the photos to change size.

However, after loaded photos work but i can’t unload it!

If i change the 1 to _mc, it’s able to unload but then tween won’t work.:ex:

Feels like i am missing something basic and it’s driving me mad.:dracula:

Thanks to anyone can help! appreciated for your time.

Here is the code:

 
var _mcl:MovieClipLoader = new MovieClipLoader();
var _listener:Object = new Object();
_listener.onLoadInit = function(_mc:MovieClip)
{
    trace("Loading...");
 _mc._x = 100;
 _mc._y = 10;
 
}
_mcl.addListener(_listener);
this.createEmptyMovieClip("_mc", this.getNextHighestDepth());
_mcl.loadClip("container.swf",1);
xx.onRelease = function(){
 
 _mcl.unloadClip(_mc);
}
