Access Objects from a external .swf
Hey i loaded a flash mx movie into a flash 8 movie, and now i need to detect if a button of the loaded movie is pressed but i simply dont know how.

i used:


var news_mcl:MovieClipLoader = new MovieClipLoader();
news_mcl.loadClip("source.swf", newscontainer_mc);

to load the movie, and i have a movieclip inside it with the instance name “read”, and i need the code to put in the parent movie (the flash 8 one) to detect a onRelease on that “read” movieclip.
