A friend just upgraded to Office 2007. When he tries to attaach a document to an Outlook email message, he gets error "COULD NOT FIND MESSAGE WINDOW." He's changed various settings (such as message format) with no luck. We searched Google and found only 2 or 3 hits, none with a solution. Those were for Outlook 2003, so it doesn't seem to be strictly a 2007 problem. Thanks for any help you can provide.
