Do you have a reference for where Nikon have acknowledged this "bug" (other than your telephone converstaion)? I've not been able to find any trace of it online.
I can't understand the tech telling you the D banks "contain Nikon specifications", because the user is able to change any and all settings in these banks, just like in banks A, B or C.
