ActionScript 2.0 :: Full Browser Sites - Scaling And Position

I'm working on a site right now where the flash player fills the browser window up to 1600x1200 res. The developers I hired are having problems with AS2 when it comes to scaling things and positioning them as the browser window changes size. While it works, the biggest problem is the aspect ratio, keeping the layout looking nice, and the footer keeps dropping off the screen at certain sizes.

Screen res closer to 16:9 looks better laid out than 4:3 and they keep telling me that it has to be proportional when it comes to positioning and scaling, although positions aren't really changing from whatever code they've used. To me, there must be some way so that if looks nice on 16:9, when it goes to 4:3 it will look good too, or even some in between size, they should be able to use code to figure out where things belong, even if it's not perfect. Instead, there are big gaps of dead space on 4:3 and it just looks like crap.

This is also true of background images which fill up about 1/3 of the page on the left or right. As we go down in size they say only a proportionate scale can be used, but sometimes the images are staying too large based on the size of the browser window and should be scaled more. Some of this may be attributed to much of the content being loaded dynamically as the client has us building a CMS, but to me, it's still coordinates and scale when it comes down to it and I don't know why raw percentages must be used instead of some more complex math.

If someone knows how this can be achieved, or can at least point me to web site that has this working properly, I can make sure they investigate further and figure this out before the deadline. I'm adding attachments to illustrate what I'm talking about. I'm using colored blocks to define where dynamic text boxes, icons, footer, images and navigation are. Arrows show where i'd like things to move dynamically.
