 From the Start menu icon, let us presume.

Of the shell window, I presume.

This should create an empty EditorWindow instance.

Puzzling.  The shell window is a subclass of EditorWindow, so 
EditorWindow.__init__ has already run once -- without the extra stuff 
added by the subclass.

That would be a good idea in general.  But first try what Chris 
suggested below.  I am about half sure that the specific problem is on 
your system.  It is possible that you need to delete something in 
HOMEDIR/.idlerc/ but lets see what the error message is.  Have you been 
using IDLE a while, or just started?
