This has been covered in a posting last year but without solution. A friend, in order to bring some tidiness into his files, decided to create several folders in My Documents and move his various MS Works letters and spreadsheets into the relevant subject sub-folders. Having done so he found that whenever he tried to Print Preview or Print the spreadsheets the error message "MS Works has encountered an error and must close" arrived. I have uninstalled and reinstalled MS Works on his machine to no avail. I had the files sent to my computer (I have Office) and they printed fine in Excel so it looks as though the problem may with Works. Any ideas out there please.
