Both image and text captchas don't have this issue but math does ! On the first verification, if will give an error but the second time, it will go through even if the answer isn't correct. I tried this several time, most of them with an empty field.

I have to use text instead which I find not much easier than image since I can't CTRL+C the selected word through Firefox ...

I can't reproduce (with CAPTCHA 5.x-3.x-dev)

On which form is that?

I tried this several time, most of them with an empty field.

That's very weird because the math response field is a required field, which means that the Drupal form API itself should block such a submission.
What Drupal version do you use? Any custom patching involved?

If you don't like the build in text CAPTCHA have a look at http://drupal.org/project/captcha_pack

I use D5.6 but I might have done the quoted instructions on D5.5 ; I haven't patched CAPTCHA. I just tried and it now works, I suppose it was a Drupal issue. Thanks for the suggestion, I noted it, but I only used text because I couldn't use Math.
