"Localhost" and "127.0.0.1" is always the same thing to me. But I remember some articles I read few weeks ago to declare some new product or new services are not recognize "Localhost" anymore.
"bradgrafelman" reminds me the problem might caused by url.
Whenever you download this cute captcha from Author's site.
CF Captcha v0.9
// Author: codefuture.co.uk
It works fine no matter what with Firefox.
But if you test this captcha with IE8. You'll get the error message if your url like this:
There's something inside the code has conflicted with the keyword "Localhost" .
The error message gone simply just replace your url in your local machine like this :
So far , I just know there's some of the code inside this captcha has conflicted with keyword "Localhost" along with IE 6 & 8. But I'm not able to pin-point it so far.
I would be very glad if anyone might able to dig deeper in this issue.
So.... hum.... Just remember this. Localhost is no longer the same as 127.0.0.1 .
