While gaming last night, I got very tired, and it seems that when the message popped up asking if I wanted to use the alternate function when striking the same key multiple times, I accidentally hit yes. I can tell because I have to wait to enter the same key twice now, and I have to wait to use the Back key more than once as well. D'oh! How do I undo this? Thanks for any help. Please disregard. After drinking from my coffee cup, I realized that under Accessories and then "Ease of Access" I found the toggle for that issue.
