Excel document creating another one when I open it.
 

In Excel 2008, I have one spreadsheet that when I open it, in My Documents it
will show another icon with the same document, but it will be unlit and will
not allow me to open it because it says it is in use.

This does not happen with any other Excel spreadsheets. Also, the original
Excel sheet I open is 501KB while the unlit same one is 1KB.

I am currently trying to copy and paste the desired spreadsheet into a new
spreadsheet.

Any suggestions??

Thanks in advance.
