Double-clicking will center map at tip of mouse pointer, the lat/lon and perpendicular distance from center path is then given beneath map.

GREEN=Center of Path , Gray=User defined offsets to center line.

#### Handy HINT #### If you are using dialup and not all tiles load on the map, press the "-" pad on the zoom control (left side of map) then one second later press the "+" pad. This will take you back to the same zoom setting, but reload any tiles that are missing. ENJOY!
