I'd had crashes on .23, but nothing this bad. I was trying to move my sovereign, hit the space bar for next turn, a message box popped up with no message but asking me for a yes/no response. I clicked yes, and the game screen went black. After waiting 30 minutes for it to terminate, I tried to use task manager to kill it, but it wouldn't die. I finally was able to reboot, but the shutdown took another 20 minutes and when Vista came back up it said Windows hadn't shut down cleanly.
debug.err is here.
I looked for a memory dump to submit to fogbugz, but there wasn't one in the directory where I'd found them before.
dxdiag is here.
