Just to update, you are correct, Chris, the file short name is passed into sys.argv. didn't need to add anything to the path. But a gotcha -- Windows didn't like my .py, clicking on the pdf causes Windows to complain about 'file x' is not a valid windows executable. I didn't research it so cant speak definitely, but converting the .py to a py2exe correlated with that complaint going away. In the end, though since, making any changes to the program required redoing the py2exe and since this is to be running on a colleagues machine, I ended up putting the handler commands into a .bat file. My hunch is that it's faster that way, too. -- https://mail.python.org/mailman/listinfo/python-list
