YES!

Well done Kenneth. That's the one. The only thing I thought would be an
issue was that I took out the <BaseMapLayerGroup> and <BaseMapLayer> from
your XML and left in the scales. It now works very smoothly without that
juddery redraw of base layers. I'm able to see the scales in Studio now even
though there are no base layers. Why can't you do that anyway? Excellent
work - you win the cold christmas turkey!
