The problem can be simpler if you're assuming a machine with only one user, or more complicated if the obvious disk location is either read-only to the user, or volatile. You also might want to clear all such flags upon an upgrade. If so, it's not just a file needed, but a sortable version string. Preferred approach is usually to respond to one of the conventional argv switches. And let the user decide. -- DaveA -- https://mail.python.org/mailman/listinfo/python-list
