riflebird on "[Plugin: Contact Form 7] Contact form 7 on Windows server"

Hi there,

Installed latest version on WP 3.5.1 and just dropped basic short code into sidebar with no amends.

Send button returns endless progress icon, no message sent.

Site is running on windows server.

Any help greatly appreciated.

Thanks,

Dave
