#2. "RE: Temporary file disk full pop-up - issue a formal complaint!" In response to In response to 1
I just sent a good oldfashioned letter to the management. At least, that is what they suggested. You can, at least here in the Netherlands, also issue a complaint through the same web form for issueing a technical question, but I guess a letter works better if you want to reach the managing director. You will find the mail address on the Nikon website.
