The World Map sectors contain nations that are not present
in the regular PGX scenarios. If you are going to edit/view
these world sector maps, install the world nations files in 
the regular pgx folders.

copy WORLD\BMP\flagsO.bmp
     WORLD\BMP\flagsR.bmp
     WORLD\BMP\TINYFLAG.BMP
     to
     PGX\BMP folder.
copy WORLD\DATA\nations.txt
     to 
     PGX\DATA\nations.txt

 After you are finished editing these map files. Restore the
original flagsO.bmp, flagsR.bmp, TINYFLAG.BMP, and nations.txt files !
