plain-win.py says ctypes.ArgumentError: argument 4: <class 'OverflowError'>: int too long to convert

[retsyo]

I tested plain-win.py on windows 10 64bits, both
Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 23:11:46) [MSC v.1916 64 bit (AMD64)] on win32
and
Python 3.6.10 |Anaconda custom (64-bit)| (default, Jan 7 2020, 15:18:16) [MSC v.1916 64 bit (AMD64)] on win32
but I get

WndProc exception: 1050D7A, 0x0024, 0x0, 0x2DFADEE3D0
Traceback (most recent call last):
  File "plain-win.py", line 86, in on_wnd_message
    return windll.user32.DefWindowProcW(hWnd, Msg, wParam, lParam)
ctypes.ArgumentError: argument 4: <class 'OverflowError'>: int too long to convert

ctypes.ArgumentError: argument 4: <class 'OverflowError'>: int too long to convert
Failed to create window:  0

btw, minimal.py runs ok
