Captcha graphic in css form builder
I'm trying to alter the clarity of a captcha graphic created with CSS form builder. I went into the wizard along this path:
Edit design > Form elements > captcha
I tried changing things like, the noise, font, grid etc. then I press apply and finished the wizard but the graphic doesn't change. I've tried it about 10 times and it doesn't work.
Can anyone point out what I'm doing wrong?
Thanks in advance.
