Here's a technote on it: http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=749eaa47&pss=rss_flex_749eaa47   ----- Original Message ----- From: Derek Vadneau To: flexcoders@yahoogroups.com Sent: Tuesday, July 18, 2006 3:47 PM Subject: Re: [flexcoders] SWF Loader Awesome explanation, Jesse. While I don't completely agree with the blocking issue the others are enough to convince me. Thanks.

Just wondering what the pitfalls of using ExternalInterface might be.

Unfortunately, this prevents you from talking to the SWF; you have to use LocalConnection, or some other binary socket way. Have you tried with Flash 9 Alpha yet? I haven't had time but I bet this'd work. ----- Original Message ----- From: "flexnewbie06" < [EMAIL PROTECTED]> To: < flexcoders@yahoogroups.com> Sent: Wednesday, July 12, 2006 8:48 AM Subject: [flexcoders] SWF Loader I am trying to cast swf as MovieClip in Flex 2.0.
