public override void AddSelectionHandles(GoSelection sel, GoObject selectedObj) {
base.AddSelectionHandles(sel, selectedObj);
GoHandle h = sel.FindHandleByID(this, GoLink.RelinkableFromHandle) as GoHandle;
if (h != null) h.CursorName = "move";

}
Note that this override has to be on a class inheriting from GoLink. If your links are GoLabeledLinks, you need to make sure the GoLabeledLink.RealLink is an instance of your custom GoLink class, typically by overriding GoLabeledLink.CreateRealLink to return such an instance.
