Sharepoint 2010 is automatically downloading Office2010 files to local machine's Recent Documents, instead of opening from library, off an emailed link.

Hi-

Please forgive me if this exact question has been asked already (if so I'm not finding it via Google or these forums), but one of my users can't seem to edit documents IN libraries, via links emailed to him.  He clicks on the link and the file auto-downloads with no Read-only/Edit option pop-up, and he can edit it (without getting the annoying yellow "this is read only from the server, click to edit document" bar up top either), but naturally his changes to these documents are only being saved on his local machine and not making it back to the library....  Our IT dept gave him a Save As workaround (that, it appears, would make a SECOND file in the library, which is not going to work for our processes), but nobody else is having this issue....  I'm thinking this is a simple settings change someplace in Sharepoint 2010 or Word 2010 (we have Windows 7), or maybe IE, or it's possible his User profile in our network needs some kind of adjustment...  anyway, any/all help appreciated.  Thanks.
