I'm mortal too ....
Just was spared by my Nikon contact to discover this buggy behaviour for myself.
I agree that field testing ought to have caught this flaw, but these days we are being accustomed to major makers rushing out their latest products with warts and all. Adobe, Apple, Nikon, Microsoft, Samsung, ..., the list goes on ad nauseam. Perhaps we, as customers, should look into the mirror and ask ourselves if we also play a part of this game in the eager of having the latest and greatest toys to play with? People spend too much time on rumour sites and stoke up the pressure on the makers even further.
