[Bug] Ideology

I ran into a case where the Ideology screen would not allow me to exit.

Here are the circumstances:

• Benevolent:
• The root of the tree had been unlocked
• Benevolent points = 30
• The next items cost 29
• Pragmatism
• No items unlocked
• Pragmatism points = 20
• Malevolent
• The root of the tree had been unlocked
• Malevolent points = 22

The unlock and done buttons remained unselectable no matter what action was taken.  Further, <esc> or other keys would not allow exiting the interface.  I had to kill the GCIII application in task manager to exit the game.

FWIW, previously I also encountered crash when interacting with the benevolent interface.  However, no crash dump was generated.  Moving to an auto saved game, then proceeding from a saved point allowed for making it past the crash point.
