IDE :: Flash Full Screen In Browser - Lock Certain Content To Not Scale?

I am trying to create a website that will full scale the browser window with all the flash elements inside but I am having trouble deciding what resolution to design in and how to lock certain content to not scale.

I am trying to achieve the effect that will consist of a high resolution image as the background for each section of the website that will full screen. Content such as logo and footer etc should always remain locked. An example of this can be found at http:[url]..... If you shrink the browser window all content stays centralised and the top and bottom footer do not scale, although the central part of the site does change. I was wondering how this effect was achieved? How does some content remain locked and others scale. I really can not figure out what dimension size to design in and achieve the high res image effect for the site. I too will require a top and bottom footer.how that site was published and constructed that would be brilliant.At present I am playing around with the following code:

fscommand("fullscreen",true);
Stage.scaleMode = "noScale";
Stage.align = "C";

I then know the publishing settings should be set at 100 x 100 percent and that when the swf is imported to the html to write the following style tag:

<style>
body {margin;0px:padding;0px}
</style>
