Thank you for the suggestion, I'll have a look at this as an alternative. I must admit, it seems a little like a 'kludge', though -- but probably a necessary one, given the limitations of the OS.
I'm assuming os.popen() keeps track of when the editor closes? Or would I have to manually fire an 'ok, now update the record in the db' event after editing the value? Much warmth, planetthoughtful -- http://mail.python.org/mailman/listinfo/python-list
