One of my users has built a little Excel thingy that, when completed, sends itself via Outlook to an internal mailbox. That's fine.
At the point of sending, a warning message "This worksheet contains hidden rows or columns that the recipient casn unhide. Do you wish to continue?" Choose OK and off it goes and nothing unhides iteself.
If, however, you then forward the e-mail to someone else, all the hidden cells unhide themselves.
Any ideas? We are running Office 2003.
