284033 Scale flash movie to min/max

I have a flash movie that I want to display at it's full, original dimension (980 x 780) in a full screen browser window UNLESS the browser window is smaller than that size (on a laptop, for instance). In that case I want the flash movie to scale proportionally smaller to fit within the available browser space. I am NOT looking for: Scrollbars to appear when the window is too small. The flash movie to scale larger than it's original dimensions no matter how big the browser window gets. Again, the flash movie should only scale smaller when the available browser space is smaller than 980x780. Many thanks.
