I'm guessing that you found the problem and fixed it. I see nothing wrong with the Electronics section.
Yes I have figured out the issue and I simply can't believe the solution. I have been discussing it on the Flash Catalyst Forum. Here is a recent post, please feel free to take a look at the page I have set up to demonstrate the issue in case you ever come across it. It is a real kick in the head.
Thanks for the tip but I just figured out the problem and you are not going believe this. I removed the buttons from two of the scroll panes and replaced them with buttons made in Catalyst and the problem magically went away. Take a look at this page:
The first three pages work just fine but the Third and Fourth pages (Outdoor & Subwoofer) will not load the SWF. The ONLY difference between these two pages are the buttons in Flash. It would seem that buttons will create a destructive error that prevents the SWF from loading.
If this pans out then the developers for Adobe really missed a big one with this. I have over 47 pages that now need to be rebuilt because I assumed that a button built in AS3 would not interfere with the SWF load.
Now this isn't something that happens all the time, I have several SWFs in this site that use buttons and work just fine but they are nested in Movie Clips and they all have to do with timeline controls rather than opening another URL. Maybe the "_blank" tag is the issue but I am required to get the user to a different page by the client's request. I can't very well go back to the client and tell him that Catalyst has an issue with that very normal request.
Anyway, thanks for the suggestion, I am spending the rest of my day republishing my SWFs without buttons just to remake them in FC. BTW, the real kick in the head is that the SWFs with the buttons work on the local files, its when you upload to a server that everyting seems to fall apart.
