I have excel workbooks created in Excel 2003 that I exchange with others,
some of whom have Excel 2007. With some (but not all) of those users, the
track changes function comes back corrupted, with the changes noted for the
wrong cells.

My users add rows, sort and filter the worksheet (along with making
corrections to the data).

Has anyone else had this problem or have any idea how it can be fixed? I
don't ever have this problem with users who use pre-2007 Excel.

Thanks so much
