Possible minor bug with the copy progress indicator. To simply back up my music and photo collections, I just copy the whole collection root directory onto my backup location. Only about 5% of the files might be new so when the conflict dialog comes up I select "Skip All" so that only the new files are copied to the backup location. This works fine, but a minor nit is that the skipped files don't seem to contribute to the progress indicator, so the progress indicator sits at 0% even though the job might be half done. I've attached an image to illustrate what is happening - more than 50% of the files to copy have been processed but the progress indicator is at 0%.
