Its been broken for awhile. I try to type 'normally' in most public area, and save the double Vs for jokes and staff areas, but its becoming a habit. I caught myself double Ving on the kids computer(which has working keys).Hmm, how did that happen, I wonder. Perhaps angrily typing w**nker in response to that company that insists you use Whatsapp?
I think its wiring. The S key fell off, and its 'exposed' (but still works). The 2/@ key doesn't work, either.
