I don't know, AgentDee. I use Internet Explorer to play .swf files, and you don't. When I use IE to play some .swfs, it comes up with a bar across the top saying that the file has ActiveX content, and it's blocking it. Then I can right-click on it and select an option for it to allow the file to play. Since you're using QuickTime to play these files, I'm not sure how to fix this. Maybe you can go to the QuickTime site and see if it has issues with ActiveX or Flash?
