I actually thought that the template might be interfering with recapcha. I attempted to address this possibility at the YooTheme forum but it appears no one wants to address this issue which is a bit disturbing. The person I'm helping with the website at seeds-of-leadership.com wants the VOX template so I have to work with that.
I think I'll take your advice and try a simple install and see if I can cut out some variables.
Your help has been highly appreciated. I'll let you know what happens over the next few days.
I thought I might experiment with Jollom but I suspect I might run into the same problem.

PS. In the lines below should I be using 'en'. Where can I learn about setting the themes. Thanks again.
$document =& JFactory::getDocument();
$document->addScriptDeclaration("var RecaptchaOptions = {theme : 'blackglass', lang : 'en'}");
Can you try with another template (more basic), I know yootheme template is using mootools library and sometimes you get a conflict with jquery or other js script...
If you have a local machine with your own apach server (localhost) you can do a test, look here :

I don't have more idea...
