What’s Up with Flash Player 10 Final???

It seems a lot has changed from the release candidates to the final version- a lot of things people did not expect.  For instance, last minute surprise changes to the Sound API… and then the previously announced security changes that Adobe has, in fairness, warned us about since Flash Player 9.

I’ve stumbled across something that I cannot understand in one of our Java applications.  This is something that worked fine in 10.0.0.525 but is now broken in 10.0.12.36:

Simply put- a SWF (any SWF) that has loaded just fine in all previous versions of the Flash Player (including FP10 RC builds) now completely fails to load.  I’ve looked at a number of different things but cannot figure this one out!

I’ll update this as I find answers.
