It worked this time with IE 7.
I just added the domains, appnitro.com and phpform.org to allow cookies:
Tools > Internet Options > Privacy (Tab)> Sites (button). Enter the full URL(s) e.g. www.appnitro.com and www.phpform.org and click "Allow" for each one, rather than having to "accept all" although I expect that would work too, but for me, I have it set at Medium level.
That got it working, according to the debug below, if I interpret it correctly, the captcha validated correctly.

$sUser code:
string(5) "GAYWE"

Validation SUCCESS!
