At first I liked the new scroll bar on Natty, but it is prone to accidental clicks.
See for instance the screenshot below:

It is easy to click "Remove" as the scroller fades out, or before it appeared, or when it fails to appear. I accidentally removed a Startup App because of this.
Is it to avoid this danger while still using overlay scrollbars?
Maybe something that would make nearby background dialogs unclickable?
