I have a workbook that is periodically updated by a coworker and e-mailed to
me. The updated workbook is renamed with a new file name such as xxx rev4 and
the date it was updated. I would like to update my workbook without loosing
my comments that I have entered in workbook xxx rev3 and the date. How do I
update my workbook to the latest version without loosing my comments?

Thank you,

Master Chief
