as3, best method for communicating between SWFs?

I’ve tried a few things but this is not working well for me :frowning:

**Movie1.swf **has a button to load **Movie2.swf **into itself and display the object once loaded (fine, this is easy).

Movie1.swf also has a button that needs to call a function contained in Movie2.swf. What is the best way to do this?

Visa versa, would it be possible for Movie2.swf to call a function contained in Movie1.swf (its parent).

What are the best ways for two way communications between swfs that are not embedded in a web page? :upset:
