after I play the game in window mode several time the buttons such as "new game, load game etc" in the main menu doesn't work anymore. I see the buttons, but when I try click it nothing happen. This is after I try to repair it through window control panel/add&remove program menu. I even reinstall several time, but it still exhibit the same problem. I don't have this problem before, this happen recently after I use the window mode to play the game.
