Kirk,
First things first.... Windows XP pro, P IV@3.2 3GB ram.
I know that all answers start with the above
I was editing a folder that contains 622 files. About a quarter of the way into the edit I noticed the the nef's had not been moved to a segregated folder, so I used explorer to move the nef files. when I returned to PM I tried to refresh the contact page but it continued to show jpg+nef. I continued with the edit and once I was done, closed PM. When I reopened PM the contacts were now correct in that they no longer had the jpg+nef BUT all of the color classes were gone! I'm back at square 1. Any ideas??
Eric
