Communicating with movies

A problem that I’m having is that any movie I load into my main swf (regardless if I load it into an empty MC or just a higher level) my mouse still recognizes buttons that are underneath the loaded swf. This can be confusing to the viewer as the pointer turns to essentially an invisible button because you can’t see the underlying button. Is there anyway to make the Flash player not recognize buttons underneath loaded SWF’s or do I have to turn to invisible upon load?

Also, I’m having trouble getting the loaded swf to communicate with the main movie that loaded it. I think I need to use the parent action but I’m not sure how. I’m trying to use code that is created and contained in the movie that it loaded, is this correct?

Thanks to anyone that helps me in these Flash perils…
