This semester I saw students repeatedly lose all their work when they tried to save a file that had RevolutionPlot3Ds in it. Sometimes the front end would crash while they were in the middle of working (as soon as they made a RevolutionPlot3D), but what was far worse was that it would crash whenever they tried to save the file. I saw this twice this semester, first when we were doing volume for solids of revolution (7.0.0 at that point), and again when we did surface area for surfaces of revolution (7.0.1 by then). Moving to a different machine and saving to the hard instead of the network did not help any, nor did downloading a fresh copy of the file and starting over. I finally told the students who were having the issue not to make the revolution plots until they had everything else finished, then make sure the file is saved, *then* do the plots but delete the output before they save again. Futzing around with this probably doubled the time it took them to complete the assignment. The crashing problem only affected a couple of students, and I have no idea what was different for them. I have not been able to reproduce it myself, but I did witness it when it happened to the students. -- Helen Read University of Vermont
