I'm using the text captcha on a registration form that an anonymous user fills out.
I have a report from one individual who continues to have the captcha fail when he responds to the question (text captcha). He's sent me a snapshot of the entire page and I've confirmed that he's using the form correctly and also that he's entering the correct response to the text captcha.

I have no problem with the form myself and I've tried it on 3 different computers as an anonymous user.

I've also confirmed that I have a zero record in the user database (mysql). I don't know where to look. Is there something in a browser that might effect the captcha? Perhaps a security feature that's been disabled? Is the captcha sensitive to a specific browser or configuration?

Any help you could offer would be appreciate. I'm sure that if this one individual is having a problem with the form because of the captcha that others may also experience problems. I just don't know where to look for a possible solution.

Thanks

If you can't reproduce the problem with your site on three different computers while it fails continuously for him, the problem is probably with his browser/network/firewall or something else on his side.

What error message does he get?
Do you know what browser is he using?
CAPTCHA 5.x-3.x and 6.x-1.x require that cookies are enabled in the user's browser

He reported that he'd been using IE6.
I don't know what firewall, etc that he may be using. I'll check. If I can resolve this and pin it down to something, I'll report back. I can't help but imagine that others may also be having a similar problem. Thanks for the quick response.

Later...I received feedback from the guy who'd been having the problem with the captcha. He had his cookies blocked. It might be helpful to have a test if possible for these situations and provide a more informative error message. I don't know if this is possible or not. I'm just providing some feedback on what the problem was.

Indeed, normally he should have received an error message "Cookies should be enabled in your browser for CAPTCHA validation."
but after some research, it appeared that this feature is only in 5.x-3.x and did not make it to the 6.x-1.x branch for some reason
I'll try to fix it
