flash actionscript: How do I create a preloader for my web site using flash actionscript that tests
whether external .swf files have been downloaded to a visitor's computer? I
currently use JavaScript on my home page to preload all my external .swf files.
I want my preloader animation to keep looping until all external .swf files
have been downloaded before the visitor is allowed to navigate my website.

Please advise.

Thanks to anyone who can help me on this issue.
Mike
