I use IDL 8.1 in win7 (64bit) and found the GSHHS maps activated
using /hires in the map_continents command gives a reasonable map.
However I have tended to use the alternative gshhs_plot commands that
allow you to specify size of elements to be plotted, which level you
want etc.. (level 1 is continent, level 2 is water mass inside land,
level 3 is island inside water mass etc). Only time will tell if I
change.
