I have a user in my department who has had a bizarre problem with Mathematica over the last few weeks (running 7.0.1 on Windows XP). He will have Mathematica open and all is well, then leave to go to class or whatever. Sometimes when he returns, Input cells are missing from the Format->Style menu (other cell types are there). Pre-existing Input cells in existing notebooks are not recognized as such (despite appearing to be an Input cell if you open with Shift-Ctrl-E) and nothing evaluates. It does not seem possible to insert new input cells in either existing notebooks or a new notebook. We also discovered that the Screen Environment is set to Slideshow when this problem happens, and all of the other options (Working, etc.) are missing from the Format->Screen Environment menu. We have tried replacing the init.m files, etc., which did not help any. Uninstalling and reinstalling Mathematica fixes the problem, but only temporarily. We have uninstalled and resinstalled several times, but the problem continues to recur. Today we uninstalled (again), and then deleted all of the Mathematica folders (from the user's profile, the All Users profile, and from Program Files), rebooted for good measure, then reinstalled Mathematica, and *still* the problem returned. We don't know of anything that would be peculiar to this particular user that would be causing this. We have contacted Wolfram Tech Support (and await a reply), but meanwhile, has anyone else seen this or have any idea what might be causing it? -- Helen Read Department of Mathematics & Statistics University of Vermont
