Error in Tutorial, or is it me?

  It's probably me, but...

  
  In the tutorial section 2.1, it says, "Running program P2_01 generates
a window like the screen shot below. Note that the axes are now
labelled, and the cursor's position is correctly given in meters."

  I ran it, but didn't get the cursor position.  Did I leave something
out?
