[QUOTE="rfwinans, post: 875280, member: 111032"] [b]keyboard: lower case letter or letters stop working[/b] I have solved this problem and used it several times successfully. In my case, it was the lower case “a”, the only letter that would not register and because my password contains an “a” I could not even restart and log in without a work-around.
