Hi Rod: It has been a while since I had to solve captchas, but I used Webvisom quite successfully. I think that when you press the hotkey that sends the captcha, there are one or more humans on the other end, one of them solves the captcha and the software automatically sends it to your clipboard so you can paste it into the proper area.
