Help! All of a sudden (didn't see it until today) about three months ago
when I'd enter data into any of several worksheets in a workbook, other
worksheets in the same workbook would get populated with the same data.

The data would get populated in the same cells on the other sheets as where
the original data was placed, and it overwrites any data in the same location
on the other worksheets.

I can find no macros which might be doing this, and I use the findlink
utility to see if I can find any links among the worksheet, and can't find
any.

There is probably some simple solution to this, but I'm not an expert with
Excel, and it is not obvious to me.

Can anybody help?

Thanks
