I get a spreadsheet from an outside company, and whenever I open up the
spreadsheet, the row numbers in the grey boxes to the left of all cells
are huge. It does this given the same font/size for the cells and zoom
level. The problem goes away when I copy the sheets to a new workbook,
but there are so many sheets with so many interdependencies that it is
not practical to copy it all to the first file.

Is there anyway to change this behavior?
