I'm not sure if anyone has had a similar problem, but I did have a friend let me know last night that he was unable to register on my site with Chrome as it was telling him he had an invalid confirmation code from the CAPTCHA output.

I tried it on Chrome as well and was able to duplicate the effect, but it seemed to work fine in Safari and Firefox.

Has anyone heard much on this and if so, what kind of information would be needed to try and troubleshoot this kind of issue?

Just tested on one of my Websites and CAPTCHA works fine in Chrome.

Email me the URL of your Website and I can test there as well with my version of Chrome 11.0.686.3
