Let's assume you start out by entering a waypoint MyHome Lat 28.00000
Lon -78.0000 and then you enter another waypoint say 24.00000
-80.0000. When you go back and click on any waypoint all the LAT LON
fields are repopulated with the data from MyHome. You can cancel out
of it but if you want to just tweek a waypoint lat lon, this forces
you to re-enter all the lat lon data if you click on any waypoint
other than MyHome. Hope I explained that ok... Mike
