Yesterday, one of our accountants computers locked up. When we got her going again, she was unable to open the Excel Spreadsheet she was in. The error reported that the file was in use by...her! We never could figure it out so simply made a copy of the file. Later in the afternoon, however, it cleared itself up. She was able to modify the original file again. Today, someone received the same message on another file. Again, it claims to be locked by the user of the frozen computer. When we looked at the file, it says it was last modified yesterday. I assume this is part of the same issue. So, the question is this: How can we get that file unlocked?
Any and all information will be greatly appreciated.
