I have a form that uses both the address field module and the CAPTCHA module.
Whenever I select a new country from the Address field drop-down list, I get an error saying "CAPTCHA session resuse attack detected."
The CAPTCHA fails to validate on submission even if the correct value is entered.

Turns out this is an issue with CAPTCHA and any form that utilizes AJAX #1395184: Forms with AJAX trigger "CAPTCHA session reuse attack detected." error

The patch in this comment fixed the problem: http://drupal.org/node/1395184#comment-5938600
