This problem is on SAGE 3.2 and 3.2.1 (ubuntu hardy, firefox) I do notice that the format of that file above not text as it used to be when I fetched it right out of .sage/sage_notebook, but is some tbz2 format from the notebook interface and 'download to a file'. Is that OK for everyone to open? I seem to be able to upload it again. regards, Jan -- .~. /V\ Jan Groenewald /( )\ www.aims.ac.za ^^-^^ --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
