Works well, but I have found a problem.
In Firefox (11) if a user gets the CAPTCHA wrong, even if they enter the letters correctly on the second attempt, it still says 'invalid' code. They must press the 'refresh captcha' button to proceed.
In IE9, the page automatically refreshes on pressing 'back'... but this erases all the form data!.
If anyone familiar with this module can spot a quick fix for this, it would be much appreciated.
