Well, OK, forests, cities, fields, etc. that are on top of the hexes are in their proper colors. BUT, all of the grass hexes and the background to city, village, forest, etc. are white. It doesn't matter whether I am playing in Poland or Guadalcanal. Nor does it matter what the weather is supposed to be. Everything is white. (screen shots attached).

How do I get the terrain to display correctly?

I am running Order of Battle (version 6.1.9) [64 bit]
MacBook Pro (mid-2014) with High Sierra OS and Intel Iris 1536 MB video card
