Help with web page browser sizing

Please look at this website: [login to view URL] - I want to see if there is a way to make it so the store part (so that there would be no blue background) takes up the whole screen.. the catch is that I want it to take up the whole screen both in a large window (such as 1200 pixels wide) and also in a smaller one (800 pixels wide) with no need to scroll in either window. As you can see, the site is completely in flash.. please bid and include what you can do to help fix this.. Thanks!
