Well, I've been having some fun with AJAX and Flash CS3. Here is the scenario:
I had 4 pages that were all the same basically except for a block of text. Each of these pages had icons indicating short video clips (usually 4 per page). When you clicked these icons, the screen would grey out and a picture of a flat screen TV would come up over the web page and play the video, you could click on the OK button and the video would stop, the TV go away and the web page would go back to normal.
NewPortfolio = document.NewPortfolio
And everything goes back to working the way it's supposed to. (To make matters even more weird, under certain circumstances you have to write "<form></form>" right inside your <form runat="server"> tag to make Flash work right as well. I've managed to get around that by rewriting some of my HTML (what precisely I did, I can't remember. That "fix" was several months ago) and as outlined above. So I think that Adobe should really look at fixing this problem before in the next release of Flash (or maybe it's Microsoft's "problem", I never know who to blame :-)
