My log on screen is white when I disable pepperflash and will return when I enable it. I've always have had pepperflash disabled and never had this problem. Yesterday was playing a game and saw I had no space bar in chat window. Check my plug ins and pepperflash was disabled during the game I was in. I have reinstalled flash player and still the same thing. Used system restore and that didn't help either.
