In Excel 2003, I compared data on two sheets within a single notebook
using
"Compare Side by Side." Now I am saddled with two copies of that notebook
each time I open it, plus the program itself is not performing as it did
before. One notebook is titled [name].xls:1 and the other [name].xls:2.
The
Help section is no Help! I would appreciate advice on how to get rid of
one
of these copies and get back to normal?
