When I have the option to show food/production/commerce turned on, all that is displayed on the map is the food part. This is true both on the game board and in the city-view screen. I'm running the game with graphics set to "high" but on a low-end video card. Also, the scroll over graphics sporadically disappear. Anyone else having one or both of these problems? If so, how can they be repaired? Thanks in advance for responses.
