My camera's firmware is up to date - A 1.00, B1.01, L 1.004. I have not been experiencing the problem that Nikon's update from B1.00 to B1.02 was released to fix. It appears that the "problem" I have been experiencing is not actually a problem - it's simply the camera behaving as intended. I had not expected both the menu and playback functions to become unavailable when the buffer was full and remain that way until it had cleared. I had not paid too much attention to one of the implications of moving to a high resolution camera - massive files taking a lot of processing. I upgraded from a D200 and had not run into this issue previously. Given all the advantages of moving to full frame and the great features on the D800, I can easily live with the longer file processing times; however, some faster cards are on the horizon.
