I am sorry to report that my experience along with that of my students is that you are out of luck. I have tried the decorruption routine, and only a small fraction of the stuff is fixed. I have never gotten a satisfactory answer about why this happens. I run on PC's both W98 and WNT. It has happened to me with notebooks that have been successfully run then saved then Mathematica exited - no obvious problems like a crash. Then next time much wailing, gnashing of teeth, four letter words, and back to the drawing boards. My solution: 1) maintain a printed copy 2) keep backups. Kevin Kevin J.
