The "Load Game" button doesn't work, nor do the "yes" and "no" buttons that appear after I try to quite the game.  Quite annoying to have to quit via control-alt-delete. 

*update* The "New Game" button doesn't work anymore either, which is strange because I started a new game last night after the 3C update.  To be more specific, all these buttons get highlighted when I move the cursor over them, but when I try to click absolutely nothing happens.  There's no sound effect or the "depressed button" animation.
