More questions, I'm afraid:

Are you running Vista, Vista SP1, or perhaps Vista SP2 Beta? Is IE8 Beta
installed?

Does this happen with any attachment or just some attachments?

If you send yourself a message with an attachment, can you open the
attachment in Windows Mail after receiving it? Can you open the attachment
in your copy of the message in Sent Items folder?

What Mail Client are you using at work? (It doesn't make sense that
attempting to open the attachment in Windows Mail would have any affect on
the attachment when Forwarded.)

What Mail Clients are being used to send these message(s) to you (e.g., MS
Outlook; AOL Mail)? Are all of these attachments to messages that have been
forwarded to you?

What change(s) did you make to your system 2 weeks ago (e.g.,
installed/uninstall something, including Windows Updates; upgraded or
replaced your anti-virus application)?

Speaking of which...

What anti-virus application or security suite is installed and is your
subscription current? What anti-spyware applications (other than Defender)?
What third-party firewall (if any)?

Has a Norton or McAfee application ever been installed on this machine
(e.g., a free-trial version that came preinstalled when you bought it)?
