Maybe a stupid question but what's that got to do with the
SegmentCanvas scrollbars?

The scrollview is the SegmentCanvas - yeah?  Erm.

In the NotationView?  Well I'm in KDE3 at the moment and I don't see
this problem - in fact the canvas is much wider than it needs to be
and the scrollbar works fine.

I was just following the comment..

Anyway, don't worry about it.  _You_ understand it.  In the best
traditions that we've just talked about I'll endeavour to _not_
understand the problem and just satisfy myself with taking the
occasional cheapshot potshot.
