I think I may have figured something that may be a clue.
I noticed on a machine running Leopard, that this was not an issue, just on my osx 10.4.11. So it is localized to Tiger.
I go to Sun to check scope out a new release/update for it, and I notice that you can't get it from them that Apple makes the Java Plug-in.
So, I'm now thinking it is an issue with Tiger's Java Plug-in, and not a Flash problem. I shall research it some more.
