NT

[Bill Tutt]

No, you've got it right. When you use the file association for some unknown
reason you can't use redirection.
If you just do: "python blah.py < blah > blah2" everything works perfectly.

My current theory is that there is a design point/bug in the file
association code that we just don't understand at the momemnt.
