I have a Workbook with all the sheets protected which includes having the Gridlines and Headings turned off. I also has the complete workbook Protected - Structure so hidden sheets cannot be opened. When I save the workbook and close it, when reopened the gridlines and headings turn back on on all the protected sheets! I can see in the Formatting palette that the gridline and head boxes are now checked even though they are gray from the sheet protection.

How do I prevent this from happening??
