"The C++ part of the .. Has been deleted, wsTaskBarIcon

[Alex Nordhus]

I need some help. I cant seem to get rid of this error.

I can program a button that will exit the program and remove the icon in
the taskbar, but I have to tie it to OnTaskBarClose.

OnExit and OnCloseWindow do nothing and leave the icon in the taskbar, I
think I have tried every option, when you double click the icon it gives
you the error.

Traceback (most recent call last):
  File "D:/Python24/simple.py", line 43, in OnTaskBarActivate
    self.Show(true)
  File "D:\Python24\Lib\site-packages\wx-2.5.4-msw-unicode\wx\_core.py",
line 11263, in __getattr__
    raise PyDeadObjectError(self.attrStr % self._name)
wx._core.PyDeadObjectError: The C++ part of the MyFrame object has been
deleted, attribute access no longer allowed.

When the program runs, you can right click on the icon in the taskbar
and close and it works.
I hardcoded the file > Exit button to do the same thing and that works
too.
However if you click the top right X to just close the window, or on
close that's when the error happens.

How do I get the close to work properly from the default window? I have
been on this same thing for days. Any help would be greatly appreciated.

Heres the code, also attaching it.
