I have a user registration form in a modal window(fancy box). I also have the form set to auto login and redirect to the current page they are on(with url parameters that I need to keep).
The problem is that if a user mistakenly mis-types the password verification the page is reloaded and the modal window is closed... You can't see an error until you open the modal again.
It would be great if there was a way to not make the submit button on the form active(open to other suggestions) unless the passwords match.
