wxpython ms-dos black window popping up in background

[icarus]

platform: windows xp professional, python 2.5, wxpython

When I double-check on my program file test.py (for simplicity I'll be
using this code below), I see the window just fine.  But the ms-dos
black window pops up in the background. On Linux, no issues at all.

How can I get rid of that ms-dos black window in the background?
something I need to add to my code? a setting to adjust in windows?
thanks in advance.


#!/usr/bin/python
import wx

appwx = wx.App()

frame = wx.Frame(None, -1, 'test.py')
frame.Show()

appwx.MainLoop()
