Case mismatch on NT

Guido,

  The problem here is that both Dialog and dialog comes with pretty
standard Python distribution for tk and mfc. I had similar prb with COM
and callDll some time ago.
  If I use the first solution, then I am kinda lost because I don't know
what those standard distribution call each other when and where.
  If I use the second way, then I cannot use either portion of tk (and
Dialog.py in Tk is pretty important) or mfc (I am not sure how dialog.py
is important, but..).
  My current thought is that I use sys.path with insert to control the
precedence during run time, but it's not an amicable situation.
  Best solution is I guess standard packages to avoid name confusion
like this. Or what I proposed earlier about searching through the whole
PYTHONPATH before rasing case mismatch err.
  Thanks for the reply,

Hoon,
