[solved] Missing captcha.inc in function captcha_pre_render_process

It seems there is captcha.inc missing in the following function

function captcha_pre_render_process($element)

at line642 of captcha.module

If you add

module_load_include('inc', 'captcha');

just under the function beginning, you can remove an error when calling _captcha_required_for_user($captcha_sid, $form_id) and then _captcha_update_captcha_session($captcha_sid, $captcha_info['solution']);

which are not defined if the captcha.inc is not include before.

hope this helps.
