Continuously Playing background

Hey,
I just created a whole flash presentation (all on one scene). The presentation contains buttons and links, and I want to create a small background animation that loops all the time, no matter where i go or what i click on through the whole presentation.

I tried making a movie-clip but the animation resets whenever i click on a button, and it looks really bad!! is there a way to keep the background animation loops the whole time even when the animation jumps to another frame??!
thanks!

Could you not just put it on a new layer on your existing scene?
