C&C:Ancients Missing Map

When I open up a Scenario from the 3.2 module, I do not get a map. I may very well be doing something wrong but I can’t see what that would be. I get the units and the terrain markers as well as the victory tracks and cards. But the map is empty so the markers and terrain are just sitting on white.

Never mind, it turns out that I’m hitting a known Vassal Engine bug on Macs. If I change the zoom level, I get the map to show.
