Possible "Transition to external SWFs" problems?

Hey, can someone give me a list of potential problems that could occur with using Voets’ transition tutorial? I’m not sure I want to post my FLA. (Private help would be great, shoot me a pm or IM)

I’ve implemented it successfully in one part of my FLA, but the second time I try to do it, the container won’t load anything apart from the initial SWF. (Button problems? Dunno.)

I’ve tried comparing the two implementations, and I can’t see any difference… :expressionless:
