Silk last night you keys the numbers 3-9 will no longer work. It is jinxed because absolutely everything else works, even the numbers 1 and 2. I think there only times not to a defect, because it came relatively suddenly and coincidentally exactly one number sequence does not work anymore. Already have a restart attempt, did not help. What I can imagine is that I have something with a cloth activated when wiping the keys off the keyboard or something like that ... Because someone knows more or has a similar problem.
