Hi stl, I don't have an appropriate machine for checking just now, but I think I wrote a note somewhere about running leobridge and some tricks to do with the environment. I would try having your script display/print os.environ and sys.path and check for differences between the command line and browser situations. That might not be exactly the right place to look, I'll see if I can find the note. Check the current directory in the two situations too. Cheers -Terry
