I'm busy trying to learn wxPython, and i'm trying to run the following
piece of code (its from the wxPyWiki tutorial):

import wx

ID_ABOUT = 101
ID_EXIT = 110

class MainWindow(wx.Frame):
def __init__(self,parent,id,title):
wx.Frame.__init__(self,parent,wx.ID_ANY,title,size =(200,100))
self.control = wx.TextCtrl(self,1,style=wx.TE_MULTILINE)
self.CreateStatusBar()

filemenu = wx.Menu()
filemenu.Append(ID_ABOUT,"&About"," Information about this
program.")
filemenu.AppendSeparator()
filemenu.Append(ID_EXIT,"E&xit"," Terminate the program.")

menuBar = wx.MenuBar()
menuBar.Append(filemenu,"&File")
self.SetMenuBar(menuBar)
self.Show(True)

app = wx.PySimpleApp()
frame = MainWindow(None, -1, "Sample editor")
app.MainLoop()

Simple enough, but every single time I try to run it IDLE gives me
this instead of the app I was hoping for:

Traceback (most recent call last):

frame = MainWindow(None, -1, "Sample editor")

**kwargs))
PyNoAppError: The wx.App object must be created first!

As far as I can tell, the wx.App object IS being created first. I
suspect a race condition of some sort here, but can anyone shed some
light on this?
