The staff has an x-coordinate as well as a ruler.  Is that what's=20

No they don't.  Spacing goes through slotChangeSpacing().  Add another=20
updateControlRulers call in there, and it works (again, sort of). =20
You'll need one in slotChangeProportion() as well.

Oh fer god's sake, not another refresh dependency on the Qt version? =20
I had at one point found that the notes vanished when changing=20
spacing, but I fixed that earlier in the week.  I assume they don't=20
vanish if you actually change the notation font?

Now, a question of my own about strange behaviour in this ruler.  At=20
the bottom of the velocity control ruler, below the bit with the bars=20
in it but above the tab, there's a blank area about the height of a=20
label or thereabouts.  This area is not only blank, it actually=20
doesn't refresh at all: if you switch to a blank desktop, for=20
example, and then switch back, you get the desktop background filling=20
the widget.  See:

What's up there?
