I have had a number of customers whose popup calendars have quit working! This seems to happen after some other piece of software has been installed. The new software changes something in Windows and "steals" the calendar. In every case, re-installing HomeSchool Easy Records has cured the problem. Your old data will still be there, but just to be safe, do a data backup first before you re-install. If your program is on floppies (and possibly an upgrade floppy), you need to install all of them, starting with the original set. If your program is on CD, just install the CD.
