Craig, thanks for the report. I have tried to decrypt the Mails in "Sent Items", but I haven't got the right private key(s). So maybe this conceals the problem. May I suggest that you create an "Execution Trace" (instructions here: https://enigmail.net/index.php/en/faq?view=topic&id=15#faqLink_6). You may also try a nightly build of Enigmail and test if this bug has been fixed already. https://www.enigmail.net/index.php/en/download/nightly-build

Enrique, does it help to wait for a couple of minutes until the gpg.exe finally have finished? How much CPU do they consume (you may have to enable the display of CPU-time column in the control panel)?

Please go here: Enigmail -> Preferences -> Basic Tab Click on "Display Expert Settings and Menus" (if not activated). Switch to keyserver tab. Clear the entries in "Automatically download keys for signature verification from the following keyserver".

Try setting the passphrase caching time to zero. You can find it at Enigmail -> Preferences -> Basic tab, "Passphrase settings".

Ah ok, gnupg.org is a trusted source. Please try Patricks advice next.

Where did you download the Gnupg 2.2.0 package from? If I were on windows, I'd stick to the gpg4win package. Gpg4win 3.0 - containing gpg 2.2.0 - is only at release candidate status.
