That scrollbar also renders the page completely unusable without a mouse. I'm on a notebook here:

- my trackpoint isn't precise enough to move the slider at a reasonable speed;

- there's no click-to-scroll-up/-down buttons, common to pretty much all native scrollbars;

- the up/down arrow keys don't work on that page, either;

- oh, and it's ugly, as well as breaking the user's interface expectations.
