Kirk,
Thanks very much for the very quick and helpful reply.
I've got one follow up question that may well indicate my lack of experience, but I am learning: If I drag & drop a selected group onto Bridge (or use 'edit selected photos with' Bridge), I would think I would want to put them into a blank/empty Bridge window for processing, but would want to leave them in their original folder when I am through with them. When I tried following your advice I wound up having to create a new folder to get the images into and opened in Bridge, and they seemed to be 'permanently' 'moved' to this new folder.
I'd appreciate your further advice on this point.
Many thanks,
--Bob
