As I said many messages ago, if your Properties dialog has a tab called 
Shortcut, then this is a shortcut file, not a python file.  I still 
don't know how you created it, but that's your "anomaly," not Windows 7, 
and certainly not Python.  Further, the name isn't  RT.py, since 
shortcuts have other extensions (such as .lnk) that Explorer hides from 
you, in its infinite "helpfulness."  It does give you several clues, 
however, such as the little arrow in the icon.  You can see that without 
even opening the properties window, but it's repeated in that window as 

And Explorer is just a tool.  The command prompt should be your home 
base as a programmer.  When something goes wrong running a program from 
the either other ways, always check it at the command prompt, because 
every other tool has quirks it introduces into the equation.

My best guess on how you created that shortcut was by using Alt-Drag.  
As you point out, drag does a move by default, if it's on the same 
drive.  Ctrl-Drag will force a copy, even on the same drive.  And 
Shift-Drag will force a move, even if it's on a different drive.

These rules didn't change between XP and Windows 7, as far as I know, 
although in some places Explorer calls it "Link" instead of 
"Shortcut".   But that's just a self inconsistency.
