wx: PyNoAppError

[SuperHik]

Hi!

Using XP SP2, PythonWin 2.4.3, any trying to use wx 2.6.3.2
When using wx, the first time I run a script it runs fine.
Second time, it rasises an error:

[Script]*************** *************** ****
import wx
app = wx.App()
win = wx.Frame(None, title="Simple Editor")
win.Show()
app.MainLoop()

[Error]*************** *************** *****
Traceback (most recent call last):
File
"C:\Python24\Li b\site-packages\python win\pywin\frame work\scriptutil s.py",
line 310, in RunScript
exec codeObject in __main__.__dict __
File "C:\Python24\my stuff\ool.pyw", line 3, in ?
win = wx.Frame(None, title="Simple Editor")
File "C:\Python24\Li b\site-packages\wx-2.6-msw-ansi\wx\_window s.py",
line 493, in __init__
newobj = _windows_.new_F rame(*args, **kwargs)
PyNoAppError: The wx.App object must be created first!
*************** *************** ************

So this happens no matter what the script is.
And it always occurs on the first line a new widget is created.
This is not a problem with the script, because it does the same
thing on every script I copied from the internet. It must be a
wx bug, but has anyone fixed it?
I googled and only found this:

*Says that runnig the script outside of IDLE fixes the problem.
That works for me too but if there is a way to run it from IDLE
that would be much easier.

Any experience on this?

Up here you should have mentioned you are doing this in IDLE, that is
your problem.

Later in your message you say:[color=blue]

This is the inevitable result of running a pair of GUIs simultaneously:
They both want control of the main program to run their idle loop, and
only can win.

I'm aware it's a wxPython question but I wasn't aware
of the group you mentioned. Thank you!

I wasn't running them simultaneously. I ended the first (and only) one
and then tried to start it again.[color=blue]
