So, the precise nature of the issue is this: I go to log in, I enter my username and password, and I solve the captcha. When I click the login button, I get the error "You exceeded the maximum allowed number of login attempts. In addition to your username and password you now also have to solve the CAPTCHA below." This error comes up immediately, even on a computer that has never accessed the forum before. It happens in IE8, IE9, FF4, FF4 & Safari.
