How do i center align a flash site in a diff res?

Hello,

I’ve been working on a flash site that works for 800X600 and a larger resolution. I’ve got the site designed so that someone who views it in the larger resolution sees the the content in th middle of the page, as well as space on the sides of the page, with no scrollbar on the bottom. I want it so that if the resolution is set to a higher level that the space on the sides of the page gets cutout. What I have when someone goes to a higher resolution is the space on the sides still there, as well as a scrollbar on the bottom.

Thanx in advance.
