Hi Craig,

This works on WIN95:

os.system(r"start /w c:\windows\notepad.exe")

It leaves a dos window displayed however. If you change the properties
of the dos window to minimized, the next time through it won't display.
I imagine it's possible to preset this, but I haven't tried. Does
anyone know how to stop this or get around it?

This worked for me on a project I did a couple of months ago. It did =
its thing for a couple of minutes then when it exited the Python script =
resumed.

...
import os
...
os.spawnv(os.P_WAIT, os.path.join(gmpath,'gmw4.exe'),
[r' /u:MASTER', r' /p:ACCESS', r' /r:69,5'])
...

spawnv (mode, path, args)=20

specified in args as command-line parameters. args may be a list or a =
