[python-win32] PythonWin won't start the second time

Mon Jul 2 21:05:40 CEST 2007

No, It doesn't crash if I import it from the python console.

I ran python.exe -v (after replacing the file with the original pyc
that does work - the one that was generated in the installation) and
indeed it recompiles because of a bad timestamp. Following are the
relevant lines from the verbose output:

# c:\Python25\lib\site-packages\Pythonwin\pywin\framework\intpyapp.pyc
has bad mtime
import pywin.framework.intpyapp # from
c:\Python25\lib\site-packages\Pythonwin\pywin\framework\intpyapp.py
# wrote c:\Python25\lib\site-packages\Pythonwin\pywin\framework\intpyapp.pyc

Of course once recompiled it crashed Pythonwin (but not the console
when importing)

This is the DrWatson report:
