early in the game, the F1 screen works okay. Later on with a bigger colony, F1 Domestic Advisor screen hangs the game. Like it's stuck in some infinite loop calculation. Uses max processing power (100% of one core of CPU.) Music comes to a halt. Game doesn't respond. Have to kill it with Task Manager. Ok so I don't like playing the 300 turn limit, I play over the turn limit and perhaps my colonies got a little larger, but the F1 screen calculation time is just ridiculous. The calculation take tortuously long even with just a few colonies. A little bigger, and the game hangs and never finishes the calculations to pop up the F1 screen. Task Manager--> Kill. Core 2 duo 2.66 GHz, Nvidia 8800GT, 3.3 GB RAM. I've attached my save game if interested.
