Filtering leaves row numbers in order instead of skipping them

[mboucher]

Hi, one of our users on Excel 2010 is having a problem when they filter a spreadsheet, instead of the normal behaviour of hiding the rows that were filtered out and leaving the row numbers in tact as say 1,3,4,6. It is renumbering the rows so they are always 1,2,3,4 etc. Is this a setting somewhere that needs to be changed? All our other machines are doing it the normal way and skipping the hidden row numbers. Thanks.
