Chris,
I am currently doing a splurge for my nephew on basics and how to get to the various controls via the menu. Covering three different models, D50, D40 and D40X, Not sure which he will get yet so its quite a long job. Kind of explains my absence from the forum. As part of that I will be doing a set on NX which I will forward to you.
Never quite got the drift of DPP so I have not owned up to a number of images in the gallery ex Canon 350D as being processed in NX.
Cannot pm you as your box is full and I have lost your e-mail address.
Don
