huh??!!!

In Outlook 2007, attached documents appear as tabs on the preview pane, which I found very cool. Today I received an email with an attachment. The attachment itself was another email. Drag-n-dropped to the mail editor in Outlook 2007. When I clicked on the attachment, the preview pane suggested me to use the progam that was used to create the file. Hmmmm. I am 110% sure that Outlook 2007 was used to create the attached message.

If I followed the direction, I would put myself into a recursive loop. Of course, double-clicking the message did open it. But I thought the error message was quite amusing.
