A small window opens each time I log on stating: Windows cannot open this file.Microsoft Works Calendar Reminders_lnk_clndisk_backup ('lnk' or 'ink'). To open this file Windows needs to know what program created it. Windows can go online to look it up automatically or you can manually select from a list of programs on your computer. What do you want to do? Use the web service. Select the program from a list. I have tried both of the choices without success.
