I am not much of a notebook user, so please take this with a grain of salt, but I wonder if the permission on the .sage directory are set up so that others can read and write to it? For the command line, that directory is used a lot to store temp files and so on. Maybe the notebook is the same way? > example worksheets to show various aspects of SAGE.
