Summary: normpath on Win32 not collapsing c:\..
Initial Comment:
normpath as implemented in ntpath.py doesn't collapse
c:\.. at all, resulting in paths that are not
normalized. Adding the following to ntpath.py fixes
this, but since I don't know how to create a context
diff, its probably not patch quality code :)
elseif comps[i] == '..' and i == 0:
del comps[i]
and put this before the final else.
Cheers.

Hmm -- I was running on a command.com box. I'm surprised
(and appalled <wink>) if the cmd.exe used by Win2K differs
in this respect from the one used by NT. Maybe it actually
has to do with the filesystem? I was running FAT32, and
there is no ".." entry in the root there; perhaps there is
under NTFS (but I can't check that right now).
Reopening pending more info.

Sorry, I should have been more specific. Your example does
work on Win2K, just not on win9x or WinNT. I know under
*nix that the parent of the root directory is the root
directory, perhaps Microsoft has modified the command
processor under 2K to be more '*nix' like. I'll certainly
abide by your decision since I have found another
workaround to my problem which avoids this situation in any
case, but it is os specific now, which is unfortunate.

Since c:\.. is a senseless path (you can't go above the
root!), I think changing it to a legal path would be wrong.
C:\>dir c:\..
Volume in drive C is HOMEDRIVE
Volume Serial Number is 2637-18E7
Invalid directory
C:\>dir ..
Volume in drive C is HOMEDRIVE
Volume Serial Number is 2637-18E7
Invalid directory
C:\>cd c:\..
Invalid directory
C:\>
Garbage in, garbage out, so rejecting this feature request.
