I have repeatedly entered a note for one individual, RIN 5704, a William Newman, and hit save.I can exit out and shut down my PAF (5.2.18).When I go back to RIN 5704, the note is there. But, when, I then go to RIN 35, a William Shaw, the last two letters of his existing note have been deleted and the note I had just entered for RIN 5704 has been transposed to the end of the note for RIN 35. When I go back to RIN 5704, his note is gone, and the last two letters from RIN 35 is there. (I always back up, and daily save a version of my file on my D drive.In checking this D drive today, I saw that a note I have added to a 3rd person, was deleted and was added to the note for RIN35.) I then clean up the two notes, and the problem repeats. After each of about 6-8 tries, the problem is the same. I am a long time user and have never seen this before. I am not cutting and pasting. Any suggestions would be most appreciated.
