Most likely caused by WindowNew Window and you now have two views of same
workbook named workbook.xls:1 and workbook.xls:2

Close one of them then save the remaining copy.

I have a large workbook containing 10 worksheets. It's quite large. Somehow -
and I don't know how, I created a copy of my workbook that open behind (next
to) my original workbook. I can see the copy by dragging a white colume that
appears on the right of my worksbook pages. If I highlight a cell or row in
the original, it also highlihgts (and changes text) in the copy. I need to
know how to get rid of that copy. Don't know how it got created, don't know
how to get rid of it. Will be eternally thankful to anyone who can help me.
