I would think there's an easy solution to this, but I sure can't figure it out.  I have a history list consisting of one airport and two lat/long positions and I can't seem to delete them.  Any attempt I make to search for an airport comes up with zero results, and I think I need to clear the departure history to get this working again.  Any advice would be greatly appreciated.
