I logged in to find a friend request, and it won't go away no matter what I do. I tried to accept, nothing. I tried to reject, nothing. Now "Notifications: 1" won't go away no matter what I do. Help?

In the box of the user who friended you's avatar click the little box. This will show the avatar clear and bright. Then go down to where it says accept or reject the request and click reject. Hit enter. A pop up will ask you if you are sure. Click yes and the pop up will tell you that user has been removed from your contacts list. That should do it.
