Morpho

Following bugs were reported by Veronique in Geographic Coverage screen

1. Morpho accepted the coordinates i entered in the NDPW, but when i
clicked "edit" in the NDPW to edit the coordinates, the coordinates were reset
to 45.0 N, 45.0 S, 90.0 W, 90.0 E.

2. i clicked on edit, but then clicked on cancel. the coordinates i had entered
were displayed in the NDPW. i finished the NDPW and the dp opened: the
coordinates that were displayed were
West:  -90.0  degrees
East:  90.0  degrees
North: 45.0  degrees
South: -45.0  degrees,
not the coordinates i had entered (even though i clicked on cancel for editing)
