How to upload multiple flash content without conflicting with the maintimeline of other previously uploaded content using Loader.loadBytes?

Question

In my project, I am trying to save all the swfs loaded in memory to make users free of delay... I can’t and I don’t want to use "Loader.unloadAndStop()" in the Loader.

I am saving all content uploaded within an Object.

For example:

var CacheSWF:Object = new Object();
var CurrentSWF:String;

function GetSWF(swf:String):void {
    this.CurrentSWF = swf;

    if (this.CacheSWF[this.CurrentSWF] != null) {
        this.removeAllChildren();
        stage.addChild(this.CacheSWF[this.CurrentSWF]);
    } else {
        var ldr:URLLoader = new URLLoader();
        ldr.dataFormat = URLLoaderDataFormat.BINARY;
        ldr.addEventListener(Event.COMPLETE, this.loadBytesSWF);
        ldr.load(new URLRequest(this.CurrentSWF));
    }
}

function loadBytesSWF(evt:Event):void {
    var ldr:Loader = new Loader();
    ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, this.saveSWF);
    ldr.loadBytes(ByteArray((evt.target as URLLoader).data));
}

function saveSWF(evt:Event):void {
    this.removeAllChildren();
    this.CacheSWF[this.CurrentSWF] = MovieClip(Loader(evt.target.loader).content);
    stage.addChild(this.CacheSWF[this.CurrentSWF]);
}

function removeAllChildren():void {
    while (stage.numChildren > 0) {
        stage.removeChildAt(0);
    }
}

But I’m having some kind of conflict when I try to load another swf. The second Movieclip loaded runs the maintimeline of the first Movieclip loaded. I have no idea how to fix this.

Example:

this.GetSWF("file1.swf"); //Eu tenho o MovieClip e MainTimeLine corretos

//Faço algo...

this.GetSWF("file2.swf"); //Eu tenho o MovieClip correto mas o conteúdo executa a função MainTimeLine do "file1.swf"

If there is no way to save the way I want, how can I clean it (the Loader) without using "Loader.unloadAndStop()" or "Loader.()"?

1. Based on the Adobe library, the Loader.() does not work for content uploaded by Loader.loadBytes();
2. I can’t use Loader.unloadAndStop() because this function does not exist for Flash 9 (the destination of my project).
