Game becomes unresponsive

Here is a weird one... repeatable on v1.00 and 1.01.

You are playing along happily, you could be out on strategic or inside the tactical layer, you press turn, your units get the new move points etc but turn cycle doesn't complete. So, you can't give commands to your units, you can't move. You can't attack and you can't end turn. If on tactical layer, you have to ctrl+alt+del to end process which you never get to do since you get DX error and application terminates.

Oh this happens in campaign or sandbox game. it is repeatable, loading a save doesn't change anything happens agin in 30 sec's or 10 min's

System specs:

Win7 Ultimate x64, Intel C2D CPU, 8GB DDR-2 asus, x48 mobo, X-fi titanium sound, GTX 275 as primary and a 8800GTX for physx.

I can post the logs if needed but I thought I will give frogboy 1 less logto go through.

And Stardock, I have been buying whatever you release without thinking since galciv:) You really dropped the ball on such a high visibility one. I hope you fix stuff soon.
