Hey Pamela - The control is a search circle type control. Basically the user drags out a circle to define a radius they want to search for data. The control itself (the circle, with the radius, etc) is on the map, but it is not anchored to any part of the map. To "turn on" searching you must call a method on the control rather than pushing a button on the map. Does that make sense? It seemed best to still override control base as it is actually controlling the map.
