anyone know why this happened recently - one day it worked, the next day it didn't - i notice it works only if i follow a link form another site to you tube, then THAT video plays once!!!! and if it try another video it wont work again - i read that youtube changed something ???? is it a flash setting on safari???? driving me nuts!
note that Adobe Flash player did get a very small update recently from version .26 to .33 to fix minor issues..
I thought I had the most recent until I checked recently.
Glad you got 32-bit to work. I had the same issue a while back and i knew that solved my problem. Unfortunately, I don't know the ins and outs of why that is the case though.
