When I switch between different map modes, I have small red stripes across all of the map and nothing on the map changes. Sadly I don't know how it is intend to look, because I don't have found a screenshot about it.
Otherwise the game works just fine ( with the integrated graphic chip ).
Does anyone else have this issue?

I had this issue on a laptop running windows XP the problem turned out to be that the the native resolution for the laptop screen was aparently much greater than the native resolution of the game and that was causing a conflict (even though the laptop was 12 yearsd old).

I lowered the native resolution of the laptop to 1024x768 the coloured bands went away and the maps worked fine.

I hope this works for you.
