Thanks for your reply.

There are plenty of viewers, but I was after a GUI editor.
Dotty seems to be the closest to this, as it is possible to move boxes around 
on the chart (if you have numlock off), but it doesn't seem to save the changed 
layout.  (At least, when I save a modified chart, then open the saved file, the 
changes are lost.)

Maybe there isn't any software to do this.

cheers
