When a signature is used, activated and the option "below my reply (above the quote)" is used there is no signature separator "-- " used. This is contrary to the behavior when using "Signature below quoted" and a new message, where the separator is used. The solution should be to show the separator in all modes consistently. (Adding the separator in the signature text definition is not a workaround, because the separator is then doubled in new messages) Screenshot of the settings for problem replication is attached.
