Wilfried, That's not the answer I wanted but it is the answer I needed.

What I wanted to do was be able to use the mouse pan mode in my control. I found the two settings:

MapCntrl.MousePointer = geoPointerHand
MapCntrl.ActiveMap.DragBehavior = geoDragHand

But my next question was was going to be on how to hold a perspective (position and altitude/zoom) while (or after) adding new reverse-geocoded pins.

I think your code is perfect for that thanks.
