Thanks for the reply. I have now installed V2.0.7 and the status now is: If a draw a "curve, 3 points" then when I select it I see the 2 endpoints and the centre of the circle of which the arc is a part (not the middle point I set to define the line) - I can drag the endpoints but not the centre. (However I can use the "properties" to reset the radius, which is the same thing.)

However if I create a spline or "spline thru points" then I can drag the control points, and that is probably what I should be using for my purpose.

I also discovered how to make the text in the status bar at the bottom of the screen bigger (cursor position etc) which was going to be my next question as the defaults were a bit small for my ageing eyesight - so I am even happier now.

Thanks again.

Now off to get to grips with blocks!
