When opening any Excel spreadsheet by double clicking the file, Excel successfully opens, but so does the following error: "'C\Documents.xls' could not be found. Check the spelling of the filename, and verify that the file location is correct. If you are trying to open the file from your list of most recently used files on the file menu, make sure that the file has not been renamed, moved or deleted." This is followed by several more errors referencing similar filenames which do not exist. The spreadsheet will eventually open, but only after much aggravation.
