Search captcha not displaying in Chrome

If I try to use the forum search functionality, without signing in, with any recent build of Google Chrome then I do not see the captcha image box. Since I can't fill out the captcha box I can't search. It's due to Chrome not displaying the insecure content on an otherwise secure page. We've just recently changed our captchas to use a secure service to avoid exactly this issue. Could something like that be done for the Novell forums? I know I can log in but sometimes it's nice just to look and search.

thanks,
Andrew
