I have a strange problem regarding Youtube videos.
If I'm watching a video, and I scroll down the screen to see the comments, when I scroll up back the video screen is messed up and in the wrong place.
Hard to explain but I have attached a screen shot.
I have Flash Player 11,3,300,257 installed and the latest Firefox. This only happens in Firefox.
If I click another tab, then return to the youtube tab, the video is in the right place again.
Hopefully someone can help me.
