A user brought this behavior to my attention recently, and I'm not sure when this was incorporated into the map control. The combination of holding down the shift button and dragging a rectangle performs a zoom-in which I am struggling to suppress. I used to take advantage of this combination for adding/removing either selected features or graphics... and this behavior now overrides everything else, seemingly to include the editor. Do I have any options here? MapViewInteractionOptions doesn't appear to have anything granular besides stopping any zoom in capability...
