1 excel file but 2 windows open

[Guest]

I receive a excel file from my workmate
when I open this file, the excel windows open and display the same content,
but the file name shown are different, e.g 1 windows show abc:1, another
windows show abc:2

And the file owner dont know why the file become like this.
Any setting make this effect ? and how to make it become a normal file?

Thanks in advance

Select the window which shows abc:2 and use the close icon for this
window (not the Excel window) then save the file - when you
subsequently open the file it will only show one window.

You get this effect by clicking Window | New Window, and this also
gives you another way of removing the duplicate windows.

Hope this helps.
