Just ran through the images in the sub directory and they all appear OK. Also did the same using Capture NX 2 and they appear OK. Capture NX has also been playing up, which is not unusual but like a lot of us I have learned to live with it
This time the error reporting box appeared requesting info on what I was doing so I have sent it to you with the file it creates.
I also came out of everything and went into the directory using windows. All the images appeared as thumbnails OK and do not appear corrupt. Could it be the Tag selection box or the directory?
Thanks again.
