Out of interest, and relating to this same problem, your message to
which I am replying here works fine with Thunderbird/Enigmail - it shows
the usual turquoise bar at the top of the screen and the "Good
Signature" message. The message that you posted this morning about
"Gpg4win on Windows 8" did not - the signature shows up at the bottom of
the screen as an attachment, and if I try to open it is give me a "bad
Signature" message. I see they were both written with Kmail, so they
should not be any different, so perhaps it is Thunderbird/Enigmail that
is at fault. As Enigmail intercepts the messages before Thunderbird gets
hold of them, I can't see why that should be though - perhaps this one
is just a fluke.

Anyway, I hope the information is useful. This is signed with
Thunderbird/Enigmail this time.
