James ... thanks for the suggestion. I have done this and the error logging usually catches all my errors and logs them. I wondered if logging itself was failing!
Philip ... thanks also. I did wonder about making the everything explicit. I've seen that mentioned elsewhere. Writing out the stdout & stderr to another file is a great idea. I'll have ago. But I think our dinner guests are starting to make comments so I'd better go! -- http://mail.python.org/mailman/listinfo/python-list
