I had this problem recently in Vista and it turned out to be a issue with the .py file association, only the first argument was getting passed to the django-admin.py script. Specifically the file association open command was:
python.exe" "%1"
when it needs to be:
python.exe" "%1" %*
unfortunately, unlike XP, you can't directly edit the association in Vista, you need to use something like File Type Doctor, see http://www.annoyances.org/exec/show/article02-500
