Hi –  
I make classes that extend movie clip, but I want to dynamicaly create instances of this class, so I really create MovieClips, but with the added features of the class. How should I create this instances? I want ‘this’ to be the root of this new movieclip with added features— It’s really giving me a headache, so please help.

are you sure what I said wouldn’t work for that? instead of creating an empty movieclip just make the library movieclip an empty movieclip. so instead of \_root.createEmptyMovieClip(“mcClip”, 0); you could just name an emptymovieclip in the library “mcClip” and give it a linkage ID to Object.registerClass() with. then instead of createEmptyMovieClip(); you could just attachMovie() the empty clip and it’ll be the same. but I guess poms is doing pretty much the same thing without the library crap… at least you have options 😃
