You might try running the dependency walker on
site-packages/win32/win32clipboard.pyd just in case, but I suspect you
won't find anything.

win32clipboard.SetClipboardViewer is a function inside of
win32clipboard.pyd, which is a DLL in the Python directory.  It,
eventually, calls SetClipboardViewer inside of user32.dll.  User32.dll
has been a part of Windows since 1992; I'm 100% confident you'll find
the problem in the Python wrapper somewhere.

On a whim, can you try checksumming the DLL?  I'm running pywin32-204. 
If you have the same version, you should get the same number:

C:\Apps\Python24\Lib>python
Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import binascii
>>>
hex(binascii.crc32(file('site-packages/win32/win32clipboard.pyd').read()))
'-0x17a3560a'
>>>

No, that's all in-memory.  If it were me, I'd load up Python.exe in a C
debugger and single-step through the function call, but then I'm not
like most people...

I did try the cookbook script here, and it works fine.
