wxPython Demo problem

I just did an upgrade to the newest version of wxPython and think this may
be the cause of my problem. I made sure to uninstall the older version
before doing the install but once it was installed the demo no longer works.
It errors out and says:

Traceback (most recent call last):

  File "C:\Python21\wxPython\demo\demo.py", line 4, in ?

    Main.main()

  File "C:\Python21\wxPython\demo\Main.py", line 736, in main

    app = MyApp(wx.Platform == "__WXMAC__")

  File "C:\Python21\wxPython\wx.py", line 1945, in __init__

    _wxStart(self.OnInit)

  File "C:\Python21\wxPython\demo\Main.py", line 724, in OnInit

    return True

NameError: global name 'True' is not defined

Is this because of the new namespace? (Import wx instead of from
wxPython.wx import *)

I'm not sure what to do at this point.

Any Ideas?

Thanks,
