i like iphoto and all, but this is really annoying...i changed the file name of two rolls from "graduation_2" to just simply "graduation", and iphoto forgot that these photos existed. i changed back the first one to the name iphoto gave it (and would have been more work to reimport) and it shows up again, but i decided to reimport the second set, and still has the dash. anyway to get iphoto to recognize the photos without the dash? currently, this is the only two photo sets that have been dashed.
