I've had this new D700 for couple months now but noticed a few times the camera would be non responsive and couldn't do anything....it's like the light meter shut things down and wouldn't wake the camera up. I tried turning on and off first and didn't do anything but after a minute or so would come back, not sure if something I did or not. I'm seeing if disabling the meter shut down will stop this from happening, but haven't tested it out on a shoot yet. Just was wondering if anyone else has had the same experience?
