Since the problem has been PROVEN to be the User Agent Strings, and I've read several other places that MS has no plans to undo what they INTENTIONALLY SCREWED UP... I can believe it. I have nine systems (5 Windows - 4 Mac) with at least five browsers in each (IE, Chrome, Firefox, Opera, Safari and others). The ONLY one that gives me FlashPlayer troubles... is IE11 on the WIn 7 machine.
