idle 1.6 bug on Windows?

[Syver Enstad]

Using Python 1.6 final on Windows 2000 Professional.

When I try to open one of my source files I get a traceback.

Traceback (most recent call last):
  File "G:\Program Files\Python\lib\lib-tk\Tkinter.py", line 766, in
__call__
    return apply(self.func, args)
  File "G:\PROGRA~1\Python\Tools\idle\IOBinding.py", line 71, in open
    self.editwin.flist.open(filename)
  File "G:\PROGRA~1\Python\Tools\idle\FileList.py", line 39, in open
    if os.path.isdir(filename):
  File "G:\Program Files\Python\lib\ntpath.py", line 216, in isdir
    st = os.stat(path)
UnicodeError: ASCII encoding error: ordinal not in range(128)

The path to the file is "E:\Våre
dokumenter\Kode\pythonscript\pythonaddin.py" so I guess it's the a with a
ring that's causing it. Any suggestions as to how to make it work?

Is it best to continue using the 1.5.2 version of Python when using Windows?
