a&w restaurant: I made up a spreadsheet on my pc which has windows 7 on it. I went and put the spreadsheet in my pc that has vista on it. It will not let me edit or change column widths or anything. Please help.|||The OS does not mater, only the software you use to open does. Save your Excel files in compatible format...not XLSX but XLS...and in the save as dialog option, save it as Excel 97 (if your other computer has 97 or higher). The newest Office Suite will, by default, use the newest file format which will not work with other softwares. Mor details if you can give us what versions you are using! Good luck!
