I was bit by the bug again.  The second cursor appeared at the bottom of the 
article buffer window in gnus's gmane reader.  Re-positioning the cursor under 
my control had no effect on the second cursor.  Re-sizing the frame from 128x36 
to 80x36 removed the second cursor.  I widen the frame to see more of the 
summary window's article titles and return to normal frame size to read the 
article window.  If there is a toggle to collapse the sender's name between the 
square brackets, more of the title string can fill the 80-columns in a normal 
frame size summary window.

  (set-frame-size (selected-frame) 80 36))
(global-set-key (kbd "s-]") 'x-frame-normal)

  "sets the wide frame size"
  (interactive)
  (set-frame-size (selected-frame) 128 36))
