Is this reproducible? If so I'll take a look at the file for you. Do you
get any warning when you open the workbook, asking to enable macros?

One of my excel spreadsheets has started automatically copying data from
one
cell to another (or rather ROWS of data) without displaying any formula or
explanation for the information. It seems to insert it about 10 - 20 rows
apart, just one cell, and slips it in before one can notice it
happening...
Can anyone suggest anything?
