Well, I seem to have found a workaround (if only I'd waited 10 minutes
before writing the preceding mail... oh well ;) :

I derive my own output window class from the wxPython one, like so:

class MyOutputWindow(wx.PyOnDemandOutputWindow):
    def __init__(self):
        wx.PyOnDemandOutputWindow.__init__(self)
        self.oldStdout = sys.stdout
    def write(self, text):
        wx.PyOnDemandOutputWindow.write(self, text)
        self.oldStdout.write(text)		# <- write to old stdout
as well as normal wxPython window

And then I install it like this:

    wx.App.outputWindowClass = MyOutputWindow
    App = MyApp()
    App.MainLoop()

And voila.

Subject: stdout output is not displayed by VisualPython when application
stops before wxPython App.Mainloop() is called

When I use VisualPython to write a program that uses wxPython, and
something is written to stdout during the creation of my wx.App
instance, but before App.MainLoop() is called, this output is not shown
in the VisualStudio IDE and is effectively lost.

This may seem esoteric but it actually happens a lot. Typically. If one
uses the wrong variable or class name in any code called during the
initialization of an object of a class derived from wx.App, it is very
hard to find out what went wrong. This seems unnecessary, since the
output works fine at all other times.

Does anyone know of a solution to or workaround for this problem? 

I am evaluating Visual Python 1.8.2, Build 2090, in combination with
Python 2.3.4, and wxPython 2.5.3.1.
