when i 1st used DC it worked brilliant, but since scanning my pictures folder ive added several other sub folders into it and i know that the sub folders contain some pictures that are the same in main picture folder but DC no longer lists all the duplictes, ive even purposely made several copies of the same picture and put them in the same folder and DC still does'nt detect the duplictes....
whats going on, why all of a sudden will it not work??
