Loading AS2 components into AS3

I have an application written in AS3 that is loading swfs written in AS2. Most of them work fine, except for ones that contain the old AS2 accordion component. Loading one results in it working correctly, but each one that is loaded after it breaks the previous one (the content no longer shows and the mask disappears). It’s not just limited to the accordion, any of the AS2 components that came with Flash Pro cause breakage. I’ve tried loading the swfs to separate movieclips, tried using applicationDomain, tried everything else I can think of. Rewriting the swfs in AS3 is not an option due to circumstances out of my control. Any thoughts, ideas, even snide remarks would be welcomed. Thanks.
