I noticed that one too.  Enigmail is not bad, except the version
designed for TB 24, XP, is probably a bit outdated considering there are
newer versions for more recent versions of TB.  But I will soon be
migrating my files to a newer latop with Win7. There, I should be able
to have smoother operations with a more recent Enigmail.
