At a guess your description of what's happening is not entirely accurate.

Although it could be, since Windows moves in mysterious ways.

Please try the following commands in sequence, with no other commands:

   python -V
   echo %path%
   ftype python.file
   python somescript.py

Then right-click the command interpreter's title bar to get edit menu. /Mark/ 
the text of your commands and results. Then /copy/ it to the clipboard (note: 
you can't use [Ctrl C] here, use the edit menu or just press Enter). Then post 
the commands and results here, /paste/ them into your message (e.g. [Ctrl V]).

And then, if you haven't already figured it out, somebody probably will. :-)


Cheers & hth.,
