My account settings on OpenPGP Security : enable PGP support, Use specific PGP
key, sign by default, PGP/MIME by default, sign non encrypted messages, sign
encrypted messages, encrypt draft messages on saving.

Nothing set under account settings Security.

Enigmail preferences / Sending = Convenient encryption settings,
Key Selection : By Per-recipient, By email addresses

For this to happen when writing an email :

1. Thunderbird preferences/Composition/General : check autosave (every 5
minutes), confirm when using keyboard shortcuts, check for missing attachments
2. 'To' field in email must be red.  This happens at random for any given email
address but I can provoke it by breaking the address.  (I assumed the red
indicated that Thunderbird considered the address broken )
3.  The 'To' field must have an entry
4. The enigmail setting for that email must be 'sign only'

Then just sit and wait for five minutes while checking the enigmail toolbar
button from time to time.

Hope this helps,
Philip
