A client's spreadsheet shows a sum function which calculates individual cells
for instance =sum(B2,B4,B6,B8) then saves and closes the workbook. When she
reopens it, the sum reads =sum(B2:B8). She couldn't duplicate the error
whilst I was there but is adamant that nobody edits the workbook. The
calculation mode is automatic and version 2007

Is this really possible???
