Ya thanks looks like you're actually right. The strange thing is that the program, when run from a graphical command line, doesn't actually open any display window. Although the code doesn't run when executed as a webserver, most likely, as you pointed out, because there is no graphical environment. I wonder if there any way I can somehow enable a graphical environment for the webserver, or do I have to re-write the underlying code? -- http://mail.python.org/mailman/listinfo/python-list
