It is '1', just as in yours. I was saying that there's no 'P_NOWAIT'
(with quotes and no 'os.' prefix). :-)

Exactly. In fact it ended up as (this is in a separate method on the
main program):

        if (sys.platform == 'win32'):
            python = 'c:/python22/pythonw.exe'
            os.spawnv(os.P_NOWAIT, python, [python, program, parameter])
        else:
            os.spawnv(os.P_NOWAIT, program, [program, parameter])

I'm running 2.2 on both platforms and with the 'os.' prefix everything
worked. :-)
