Loader Class misbehaving with multiple loads of AVM1 swf

Hello, I am using the Loader Class to load a AVM1 swf written in AS2., everything seems to function the first time it is loaded, and if I ‘trace out’ [COLOR=Blue]this[/COLOR] from the main timeline of the AM1 swf, I get ‘_root’ , but the second time the Loader.load() method is invoked, after the AVM1 swf is added to the stage again, I get something like this, _level0.[ApplicationName]0.instance63.

Does anyone know why the reference of this seems to change after a swf is reloaded?
