Just a guess...

But it sounds like they're hitting File|SaveAs instead of File|Open.

This would pretty farfetched--is there a chance that someone modified their
toolbar so that file|Open does the wrong thing?

Do they see "Save As" or "Open" in the titlebar of that dialog?

I have a couple of users that are constantly overwriting a workbook on the
network with a blank copy of the same name. They say when they do file open
and open the file they get a message that the file exists do they want to
replace and if they say yes it overwrites the good copy with a blank. I have
them set to not use offline line files but that didn't stop the problem.
