Hi there Gary, thanks for reporting this! Can you give me a link to a particular video where this happens, so I can try to duplicate it?

Any Youtube.com video. 

When I am watching a video and I scroll down to maybe read comments about the video while it is going on, or if there is something on the page that I eye related to that video I look at but have to scroll down, the video images stop to a single image, but the sound still goes. If I move my mouse around over the browser the movie functions. I have seen this also on vimeo. I was here and it happened.

Any place where there is video. When I watch the same video on Safari, it doesn't happen.
