Was it really necessary to implement your own scrollbar? It's absurdly slow (and therefore annoying) on Firefox/Conkeror, and seems entirely redundant when the browser handles scrolling perfectly fine.
I thought it was just broken for the scroll wheel on the mouse, and therefore if you had a fancy apple trackpad you could swipe easily and quickly through the content.
I have a weird issue in Chrome where setting the video volume causes the page to scroll down until only the lower half of the video was visible. I am unable to scroll back up and have to refresh the page.
I agree. All I saw was a "Blast! This video can’t be played with your current setup." message, and thought that was it. Up/down cursors and scrollwheel don't work. I just started clicking on elements randomly to see why on Earth this might have been upvoted. Eventually I somehow triggered the scrollbar to move down and saw that there was some text to read!
