Be aware that password protection is extremely weak in Excel. Any user who
wants to can get at the hidden sheets, no matter how hidden, if they want
to. If a user should not see the data, then don't send it to them.

I have a workbook to which only i have the password. All other users open
it
as "read only". Within the book are some hidden worksheets. However, even
when the book is opened as "read only", a user is able to unhide these
sheets. I've tried using "Tools-Options-View-Hide Tabs" &
"Format-Sheet-Hide", all to no avail.
Is there an easy way I can prevent this?
thanks in anticipation.
