Sue: Don't edit files that are in emails. Always detach first. Open ANY
other Excel file from an email and hit File-Save as. Look in THAT list
(OLK...something) for your file. See... it gets saved in a temporary folder
in your Outlook data store (or something), and when you open it again, it
becomes overwritten, so I think you're SOL. ALWAYS save attachments to the
local PC before working on them.
