Flash Window Resize Questions

I’m sorry if this has been asked before - I searched, but couldn’t find the exact answer I was looking for.

I’ve created a very, very basic flash file, and put the .swf into Dreamweaver (CS3). I set the width and height to 100%, and the margins to 0, so that the .swf will expand or shrink with the window resizing. Everything works great, but my only question is this:

How do I make it so that the .swf will stop shrinking after a certain point. I.e., I don’t want it so that someone can shrink the window (and the .swf) to a ridiculously small size. Let’s say the .swf would stop shrinking after 600x400 px…or something…

Thanks in advance!
