This is what I want to do:
1) have a "holder" swf that contains the background img and SCALES to fit the browser window.
2) have the "main" swf inside the holder that DOES NOT SCALE with the holder.
An example can be found here:
so far I've been able to scale the holder to fit the window as I wanted using the "noborder" and 100%x100% html attributes. I've been fooling with the stage.onResize function and listeners, but they don't seem to work right, partly because I don't think they're supposed to be used with "noborder" set to true.
