Was a few turns into first game and was trying to move the sovereign around some while the game apparently thought I wanted to place a building.  I remember distinctly moving it twice before the game became unresponsive and died.  Had to put comp in standby and bring back up just to end program.  Good chuckle at the send report screen saying the title was 'Turn based fantasy game'.  Oh, I had also just loaded the game as with the save game popup being broken right now, I accidentally pressed the main menu button after saving.
