Something has started to happen with Chrome.
The waterfall doesn't always display properly again when scrolled left or right, and it sometimes requires a F5 refresh to start it up again.
I don't know when this started version wise, as I haven't used the KiWi quite as much recently, but I used it quite a lot today and noticed it fairly frequently.
I think may have had a similar problem once before. Has anyone else noticed this ?
