Scale down entire Flash Project?

Hi folks,

I have done a search for this but I can’t seem to find anything specific to what I am trying to do. I have a Flash CS3 slide presentation which was created at 1024x768 for projection purposes. Now, I have been asked to create a version of the presentation for the web which would need to be much smaller, say 480x360 for example. Changing the document properties is easy enough, but how would I go about scaling all the content down? Any help would be greatly appreciated.

Glen
