An unwanted second captcha is being created and the UI does not update when the second captcha is created.  There are no other Ajax calls on the page that are causing this issue.

We have extended the BaseCaptchaCachingProvider and are now saving the image in the database. After making this change, the image is no longer grayed out; however, validation only succeeds after every three attempts. When we check the database, we notice that a second key with a different image has been added before the user clicks the submit. On the user interface, we still see the old image.
