Turn generation issues

[Epaminondas]

Ok, I am having a severe turn generation problem even with the new computer I got. I clocked my recent turn (on the Parganos map with 1 AI opponent left, on the year 12th), and the "Thinking" part of the turn generation alone lasted 9 and a half minutes. This is extreme obviously and seriously hampers the game experience.

So is there anything I can do about this? Should the computer be "Thinking" that long?

The best advice I got thus far was when someone once suggested that I run 2 games simultaneously and play one while the other game is in its turn generation mode. But here's the problem with that solution. It seems like the Alt-Tab does not always work properly when the Dom III is in its turn generation mode and I cannot get out of the game until turn generation is complete.

Any solution? I am very frustrated. And I'd have to say that the turn generation speed (or the lack thereof) is the biggest problem in this otherwise novel and excellent game.
