I've never had a problem seeing videos on websites before, but for the past
couple of days-- even before I upgraded to 10-- videos on websites won't
play. They either say they are connecting, then do nothing, even if I click
play; or, I see this half of a box with all the controls (stop, play, pause,
etc.) but I can't click on them.

I know this question has been asked before, but for some reason when I click
on the question, it won't load.
