Thanks for the pointers David, this will give me some things to investigate. As for me, I'm a long time and regular Linux user with some XP tossed in. I use the PIL under XP at times, but this problem is happening to someone I know who is using both Vista and Windows and can't get the basic thing to work so I am trying to help. (I have access to a Win 7 VM for testing purposes at least). If I find a work-around or fix or concrete cause I'll post. In the meantime if anyone has any other ideas or fixes/suggestions, please don't be shy :-) Thanks, Esmail -- http://mail.python.org/mailman/listinfo/python-list
