I did "Find" on Flash, and found Flash "System", and found many Flash folders inside there, and saw that most are from my bank, Flickr, dot mac, Comcast, Pandora, youtube, and a couple of shopping sites(but not Amazon).
The little folders have a # in front of the site name. And when I open the folders they all say "settings.sol". That's as far as Ive looked. Some I don't recognize, but I have not trashed any of them.
Looks like Ive v. 7 on this(Panther) Mac and v. 9.0.16.0 on the G5.
I guess I will just leave it alone, as no matter what site I go to, Ive not seen it again. And wouldn't want to mess it up, as I can shop or view our bank stuff and listen to Pandora without any problem on both Macs. It was just youtube that this happened with, and just once.
Thanks for all this info, it sure is interesting,
Jane
