Gnus/PGG password problem

I've been using mailcrypt for years, but someone recently pointed out
that MIME is now the "standard" way to do signing. Fair enough, I'd be
happy to make the messages look a little less awkward in
non-encryption aware readers anyway.

So I'm trying to switch to PGG. I've removed all the mailcrypt stuff from
my .gnus file and replaced it with:

;; PGG
(require 'pgg)

(setq pgg-cache-passphrase t)
(setq pgg-passphrase-cache-expiry 3600)

;; Emacs should always decrypt and verify emails automatically
(setq mm-verify-option 'always)
(setq mm-decrypt-option 'always)

;; Automcatically sign when sending mails

(defun will-you-sign ()
  (interactive)
  (if (y-or-n-p "Do you want to sign this message? ")
     (mml-secure-message-sign-pgpmime)))

(add-hook 'gnus-message-setup-hook 'will-you-sign)

In a few minutes I'll probably get around to replacing will-you-sign with
sign-always, but that isn't the issue.

With the setup above, using Gnus 5.10.2, when I send a signed message,
it asks me for my key three times in a row (apparently once for each
destination that the message goes to, the outside world, the current
group, and the monthly archive group).

What's more, if I send another message right away, it asks me three
times again. It appears not to be caching the passphrase.

Clues, please?

                                        Be seeing you,
                                          norm
