We're seeing an issue in Excel 2007 related to sorting data using the sort
within an auto filter. Excel behaves differently if you run the sort from
the filter drop-down or if you run it from the Ribbon. From the Ribbon, the
sort function works every time for all columns. From the drop-down, Excel
only sorts the filtered columns.

This behavior is different than 2003 where Excel sorts all of the columns
regardless of how many columns have filters. This is a problem since there
are manyspreadsheets created in earlier versions of Excel with filters on
only some columns and there is no warning that the data will become
inconsistent. Any assistance is greatly appreciated.

Below are the steps to recreate the problem.

1. Create a blank spreadsheet in Excel 2007.
2. Populate the first row with column headers.
3. Populate a few rows worth of data.
4. Select some, but not all, columns and click the Filter button on the
Ribbon. This applies filters to the columns you select, not all columns.
5. Use the sort feature in the drop-down menu in the column header to sort
the data.
6. No warning is given. Only filtered rows sort. Your table now has
inconsistent data
