I appreciate all the responses. It IS possible that wx and/or python is whacked on my machine. I've got python 2.2 and 2.3 installed, I have installed and uninstalled 2.4, I've had about three versions of wx installed along the way for different programs, so it is possible that it is just my machine.
Nevertheless, I came here looking for ideas, and you've given me some good ones: some I had already tried (but I like validation) and some were new to me. Thanks, all. -- http://mail.python.org/mailman/listinfo/python-list
