Yeah, I just reproduced your bug ... Seems like the reference to _root
gets screwed up on subsequent calls. What's *really* interesting ... If
I comment out the cleanup in your AVMLoader class, I can *crash* Eclipse ...
if (_loader!=null)
{
//_loader.unload();
//removeChild(_loader);
//_loader=null;
}
I would file a bug ... Note that your publish path for your FLA is
incorrect. It should be bin/AVMTestMovie.swf but its bin/AVMMovie.swf.
