   Although the reCaptcha plugin works well (2.9.1), I get a JavaScript error in Firefox 3. Firebug shows the following error: "sub is null".

   The source code is:
   

   var sub = document.getElementById('submit');
   sub.parentNode.removeChild(sub);

   I don't know why this error happens... maybe because "submit" is not a unique name or it is defined AFTER the script?

   OK, problem solved.

   Actually, the call to the 'comment_form' hook in my template was BEFORE the "Submit"-Button, therefore the ID 'submit' wasn't even initialized when the JavaScript called it - hence it was NULL.

   I have adapted my comments-php (rather than the plugin), and it works fine now - no JavaScript error any longer.
