Hmm...there is no Add-ons > Plug ins. ??? Just Add-ons. When I type "about:plugins" in the address bar, it shows me all the plugins installed, and it shows the latest version of Flash Player is installed.
Yes, I see flash on the "about" adobe page; it works, but it also stutters, ever so slightly, when it's drawing out the words.
Yes, this happens on all Flash content, Hulu, Youtube, etc.
I appreciate you replying and trying to help me solve this. I seriously can't believe that you don't have any stuttering in Leopard! So strange...
