Since yesterday when I open an attachment that is a jpg file, it opens up
Microsoft Office Document Imaging program and a message pops up saying "The
selected file is not a valid Microsoft Office Document Imaging file".

Previously it would open the file using Internet Explorer 6. This is so
frustrating and I don't know how to set it back to opening using IE6.
Aaaaargh....!!!!! Please help! I am using Microsoft Outlook instead of
Outlook Express.
