OK, sounds like you are running IDLE (Python GUI)?

I normally just run my scripts from a command prompt...

Just tried running the scrpt from IDLE and it works - the path problem disappears

So... from IDLE - open the file, then hit Run Module from the Run menu (or F5)

Bear in mind, it is/was a QUICK AND DIRTY script for a specific job, so it only takes some of the data. I only really put it up to show what was possible using Python.

Cheers
