Hi, I'm running IG on a Mac with OSX 10.4.8 with a Dual 1.6Ghz PowerPC G4 with 896MB ram.

Although I expected not to get the best graphics performance I have a big problem viewing the map area. All I get are grey clouds that obscure the entire map with only the tops of buildings and pieces appearing. Is this a problem with my hardware or am I not making a correct graphics option selection?
Or is the game supposed to do this?
