Flash resizing and full browser screen size

Ok, I have searched the forums and found ways that are close to what I want but I cant seem to find a method that works. What I am trying to do is create a main swf that is the fullscreen background of a browser window. The main.swf then loads another swf on top of it. The problem is I dont want the swf that is on top of the main.swf to change sizes or scale when the browser window is resized.

I tried both
fscommand(“fullscreen”,true);
fscommand(“allowscale”,false);

and didnt get what I was looking for.

I know how to do all the html formatting for the embedded flash file, I just cant figure out how to get in working on the flash end.

Can anyone help me figure this out?
