Hi,

A workbook that I am currently using at work keeps splitting into two
workbooks, but only when I open it up. (When the workbook is not open, it
only appears as one file, File.xls, in the file list.) After I open up
File.xls, Excel splits it into two workbooks and in the top address bar calls
them File.xls:1 and File.xls:2. If I make changes in one and save, it also
saves the changes in the other one. How can I get it to be one workbook
again?

Thank you,
Katherine
