Unable to unload external swf which is using runtime sharing

Question

Unable to unload external swf which is using runtime sharing of some symbols and classes.
Due to this problem i am unable to load another swf or the same for the second time and getting errors at runtime.
It works fine when the swf is opened in IE.
Can anyone please help me in solving the issue.

Answer 1

thank you
i have tried to use   this.parent.Click_To_Close  but it gives compilation error
i checked the tutorial about custom events i think its little complex for me now to understand the typeriter app.
also i cheked the similer thread and tried to test that code myself..i found that the last block of main movie does not works and does not unload the loader2. however  all the trace are showing in the output windows that i added to check the code but last trace from the main movie is not showig...   
trace("child removed from Main Movie") 
so if this can work somehow i will use this method of event dispatch in my application that i am working...
Thank you
-----main movie ---------
var loader1:Loader = new Loader();
var loader2:Loader = new Loader();
loader1.contentLoaderInfo.addEventListener(Event.COMPLETE, assignMovie1Listener);
loader1.load(new URLRequest("movie_1.swf"));
loader2.load(new URLRequest("movie_2.swf"));
addChild(loader1);
addChild(loader2);
function assignMovie1Listener(evt:Event):void {
      MovieClip(evt.currentTarget.content).addEventListener("eventTriggered", removeLoader2);
            trace("listner is listning..")
function removeLoader2(evt:Event):void {
      loader2.unloadAndStop();
      removeChild(loader2);
         loader2 = null;
            trace("child removed from Main Movie")
//------------- movie_1.swf code:
removeMovie2_btn.addEventListener(MouseEvent.CLICK , removeMovie2);
function removeMovie2(event:MouseEvent):void
      dispatchEvent(new Event("eventTriggered"));
            trace("event triggered form Child Movie-1");
as u can see when i click close button its triggering the trace from movie-1 but its not unloadign the movie2
