Oddly enough, the MacBook Air, with newest versions of Flash and Safari, (and which shipped with the latest OS) is the worst offender. I'll update the laptop, though, before I hand it off to someone else in the family.

Assuming the tale the guy who tested out new Macs at the Apple Store is true, on top of my own experience, it sure sounds like a Mac software glitch. It's got to be the apex of irony, when Apple, itself, is operating a problematic site.

In any case, if resetting Safari will wipe my passwords, maybe I'll finally get around to changing them into something actually worth using, as I go. That would definitely qualify as a Very Good Thing, even if it doesn't fix the video/transaction failures.

I'll check out Cookie Stumbler too. Thanks.
