You can protect the workbook's structure.

This'll stop the user from inserting/deleting/renaming/moving sheets.

In xl2003, you can find it under:
Tools|Protection|protect workbook|Check Structure

Leave Windows unchecked.

Give it a memorable password. But be aware that this password is easily broken
by anyone who really wants to.

there are certain worksheets I want to keep from others eyes.
Thanks
