It occurs to me that the MapContinents function might be using GSHHS
shoreline data, and that might be the problem. So, I tried the same
thing with high resolution GSHHS data:

mapCoord = cgMap('Equirectangular', LIMIT=[35, -6 , 37 , -4], $
Position=[0.1, 0.1, 0.9, 0.9])
cgDisplay
mapCoord ->draw
cgColorFill, Position=[0.1, 0.1, 0.9, 0.9], color='sky blue'
cgMap_GSHHS, 'C:\IDL\data\gshhs\gshhs_2.2\gshhs\gshhs_h.b', $
Map=mapCoord, Color='tan', /Fill,
cgMap_Grid, /Box_Axes, /Label, Map=mapCoord

This works perfectly, too. So, I don't think there is anything wrong
with the HIRES data. I think the problem must be in MapContinents.

Cheers,

David
