Under windows, the function that displays help gets redefined in ess-iw32.el. In
that version, there is no provision for displaying a default for the help file
(normally the word at point). I don't know lisp well enough to know how to fix
it. For my installation, it worked simply to redefine the
ess-display-help-on-object function back to its original (a copy was made in
ess-iw32.el). So, after adding the following to my .emacs, I now get a default
when launching help:)

(fset 'ess-display-help-on-object
      (symbol-function  'ess-display-help-on-object-original))
