:lol: :lol: :lol: :lol: Now I can watch the happy little penquin and be just as happy!! Thanks a bunch and glad to see you don't allow jerky messages! If I could put a message under your YouTube video that I got this web address from, I would comment there, too. YouTube has changed and I can't access my comments or 'favorites, etc. " anymore without starting a network, using my full name, etc. and I don't want to get into all that. At any rate, I really appreciate your help!

Macintosh is abbreviated 'Mac' not 'MAC'.

MAC = Media Access Control
Mac = Mac(intosh) computer

I've tried all of the above... to the best of my ability, that is(!)

I've reinstalled Adobe's Flash Player, I've reset Safari & repaired disk permissions. I'm still a bit foggy on how to opt out of HTML5 trial, and/or I'm not sure I have it...

NOW, SOME of my YouTubes work, and some DON'T. It's quite puzzling. It would seem that I need to look at alternative #1, but I'm still not certain on how to check it, etc. It's just not clear.

I seem to have encountered this problem AFTER installing the new Adobe Flash Player. By "this problem", I mean that I go to YouTube, using either Safari OR Firefox, and the screen simply stays blank. And there have been no warning messages.

OH........... and also, though I had 48 symbols left, it indicated that this message is too LONG !?!?!?
