[python-win32] context_menu.py crashing Explorer

[Mark Hammond]

As far as seeing the print statements, you can modify the source file to 
have "import win32traceutil" at the top, and in another console run 
"python -m win32traceutil" - the print statements from the source file 
should them appear in the console running win32traceutil.

However, I don't think this will help you find the crash - it might let 
you see what *does* work, but probably not what doesn't.  Ideally you 
would attach explorer to a debugger and see where it crashes - even 
without debug symbols you might get some clues as to where it is 
crashing.  Given your other alternative is to write a shell extension in 
c++, you probably already have access to the tools necessary.

HTH,
