I'm have IE9 beta in stalled on a Win 7 - 64 bit with Office 2010. In the past I've been able to click on a mail link and send a compose email windows would pop-up with the "To:" address filled in. This was working perfectly with IE8. After installing the beta of IE9 I'm receiving an error messages stating "Defualt email client has not properly installed". Any idea why IE9 doen't work with Outlook 2010?

Yup, that's me It's wasn't clear where to post IE9 issues.

Thanks for your assistance.
