I've submitted a bug ticket a week ago, and continue to be unable to retag untagged face clusters using the face analysis menu.  What is happening is after Peakto "completes" face analysis on source catalog import, many otherwise detected faces remain marked "untagged", and when I attempt to correct them, Peakto starts the process, but hangs with activity window showing 0% progress.  Is anyone else experiencing this issue?  Any ideas?
