I never had any ghosting (coming up on a year of ownership like the other pre-orderers) until I ran the last software update. Could be a coincidence, could not. Immediately after the update, I now do get a lot of ghosting, but it always removes perfectly with the refresh button. Could anything in the latest update have caused this? I know it could just be a year old machine, and it's not a problem because it clears up. It's just curious that it coincided exactly with my software update.
