Protection in openoffice spreadsheet created .xls files
I need to use openoffice to create and/or modify .xls files. The problem I am having is that when I have protected either sheet or workbook on my Linux box when the .xls is opened in exel on an M$ box, no password is required to unprotect. It is very frustrating, and I am sure I am missing something basic!!
FYI I am using Kubuntu Intrepid with the latest OO in the repo's
