Thanks Tim. There weren't that many so I'll enter them again and make sure I save them to the cloud this time.
My waypoints tend to be small airfields or visual features that are not on the SD maps. At present I find them on Google Earth then enter the lat and long to create a waypoint in SD. It would be nice if this could be done without the data entry while in the "View on Map" window. I guess this could be difficult / out of your control though.
