To clarify, at that site I'm migrating from zope2.5/python2.1/win2k
box to zope2.7/python2.3/winxppro. When "it used to work" I was
referring to my product running within zope as a service. For initial
debugging in the new environment, I started in console mode. Once
things stabilized, I started the service up and the problem surfaced.
Backtracking through the code I found the service starting the
application as per my earlier post with pythonw.exe which led me to
the direct comparison.

It did look like there'd been some significant refactoring going on
within zope and windows service interaction, but replicating the
effect directly using pythonw vs python seems to take that out of the
picture. (hence the post to the python list and not the zope list. I
really should remember that python-dev is an open list now...)

At this point, I won't be back to that site before next week, although
I may take some time to test this weekend. It sounds like I should
rework any areas that spew output to the console. Is there something
better than checking os.path.basename(sys.executable)?

That'd be too easy! Just ask that other Tim...
