Excel 2007/PC, mysterious duplicate rows

[Jeffrey Green]

I don't usually use 2007, but can and do sometimes. I usually don't look at my data as I slice, dice, copy, paste, sort, etc. But 2-3 times now in the last month or so I did my normal slice/dice, etc. and my boss sent them back to me because there were duplicate rows of data.

Today, i started with, what I know to be a clean worksheet . . no duplicate rows, etc. So I copied, pasted delete some interior rows, auto filtered for a particular company, etc. Low and Behold, 4 duplicate rows show up . . . .

Has anyone else had this happen in Excel 2007??

I am 99.999999999999% sure I am not doing this . . .
