noscript version not displaying the textarea to post verification code into

I have added the noscript html from the Google instructions to my login page: 

This produces a 2 word captcha as expected but on successful verification I get an iframe saying ''Copy this code and paste it in the empty box below" and a field with the code in it (see screenshot). However, the textarea to paste the code in is hidden by the iframe. Surely this should be a part of the frame so it sits just below the text? Has anyone got this working and can tell me how it should look on screen? Thanks. -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
