This morning when I tried to open an existing Excel workbook, it tells me that it is already open. There is nothing on the screen. I closed Excel (using 2003 version) and restarted computer also. I tried to open the file again - nothing shows up on the screen. When I attempt to open the file again I get a message that says "(file name).xls is already open. Reopening will cause any changes you made to be discarded. Do you want to reopen (file name).xls?". Even if I reopen the file, it still does not show up on the screen. Can anyone tell me what has happened to my file that I was using yesterday? And how can I remedy this issue?
Thanks so much in advance,
