Prevent scaling in interface

I have a class project site I am working on: http://matt.hopkins.net/isd2/site/

I would like to have the flash movie to scale to fit the browser window, but I don’t want the objects in the movie to scale. Object are the nav, and the movieclip containers that hold the loaded in swfs which contain the content.

I’m sure they’re a simple way to accomplish this, I’ve just exhausted my own efforts in figuring this out.

Thanks
