Thanks again for the help. I entered the import statements you suggested into the Python Shell and they gave me the same error message. (Neither did visual_all, but of course the print statement worked.) Since I use Python 3.2.3 I've had trouble with programs and modules designed for Python 2 and many programs don't work on my 64-bit system. I was hoping it was a common error that newbies encounter. Thanks again, Python fans. I'll keep you posted on my progress! Peter -- http://mail.python.org/mailman/listinfo/python-list
