Hi Martin,

Yes. Setting scroll-bar-width to 14 reduces the indent. At 13 and at 12
the indent is gone and the window (Emacs frame, that is) looks correct.
And at 11 and 10 and smaller I see the scrollbar being noticably clipped
(it is too far to the right and the right side of it is missing).

I'm guessing there must be a way to get the correct value from the
toolkit rather than hard coding it to 16?

Thanks.

Regards,
Neil.
