I saved a workbook with a digital signature, but now want to remove it so I
can edit the workbook. When I try to remove the signature, signature is
"invalid" and I get a message saying it can't be removed because workbook is
read only. Message says "to add or remove signatures, enable editing, save
changes & try again." How do I enable editing? Most of my options are greyed
