I agree. The first time I saw the Google wave scrollbar I thought that it was a visual glitch because it looked like the scrollbar had somehow floated outside the frame. And the most disturbing thing in my opinion is that using my mouse's scroll wheel is very laggy, especially on longer waves. I would much rather they let the browser handle scrolling and scroll bars naturally. It would be much more efficient.
