How to completely DESTROY the new reCAPTCHA?

I need to completely destroy the reCAPTCHA element, but it has no destroy() method... Is there a manual way to do it? I need to do it because the page with the reCAPTCHA is loaded with Javascript, but it only works the first time, other times the page loads I get javascript errors (Blocked a frame with origin "http://bit.ly/1eCg7Yn" from accessing a frame with origin...) -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
