When I make a new clip in a library ,or a new sound, I have
an option to export it in a first frame. If I turn off that option,
how can I export it later using actionscript? The problem is that a
huge sound file, for example, would normally download itself before
preloader has a chance to show up. So this is not a question of how
can I download another file, but how can I choose which part of a
swf to download first?
