It sounds like you may have some columns that are hidden.

I'd do this:
edit|goto
Type:
1:256
Format|column|Unhide

If it happens whenever you create a new workbook, you could have a template
workbook that has those hidden columns.

Look for Book.xlt in your XLStart folder and open it and take a peek (and fix
it).

Thanks.
