Hi Dick,

I believe excepthook is simply set by the originating Exception. If it's
not set there there's nothing to print; In fact the Python API manual says
if you call PyErr_Print() without there having been an error it would
result in a fatal error!

On Windows, the failure for the scripting console is:

Traceback (most recent call last):
  File "<string>", line 2, in <module>
  File
"D:\launchpad-dev\kicad-winbuilder\kicad\bin\pylib\wx\py\__init__.py", line
8, in <module>
    import crust
  File "D:\launchpad-dev\kicad-winbuilder\kicad\bin\pylib\wx\py\crust.py",
line 15, in <module>
    import editwindow
  File

line 8, in <module>
    from wx import stc
  File "D:\launchpad-dev\kicad-winbuilder\kicad\bin\pylib\wx\stc.py", line
10, in <module>
    import _stc
ImportError: DLL load failed on
file:'D:\launchpad-dev\kicad-winbuilder\kicad\bin\pylib\wx\_stc_d.pyd'. The
specified module could not be found.


But I can assure you that this file is good and does work. I can step
through the code surrounding the script console generation and then it
works okay, only occasionally will it fail with the same message.

I can run up python normally and run pretty much the same code as an
example and see and use the PyCrust interactive scripting console. So I've
no idea why it's complaining.

Best Regards,

Brian.
