Discussion was SCH not PCB - subject heading reflects this. So discussion
of PCB and gerbering is off the mark and confusing.
In Sch an arc displayed as a full circle should behave as a full circle, it
doesn't always - this is a bug.
We now know one reason for difficulty in picking up some circles thanks to
Eric. A small mouse movement between clicks can make a huge difference in
the ability to edit/move/delete the circle. Either fix it to allow for zero
length arcs (fix the display) (yuk) or take special action when the start
and end angles are the same and add 360 to the end angle and we have
correctly functioning circles - in schematic remember. Not PCB.
