Strange, it shouldn't really matter.  Unless you're accidentally
invoking initScroll instead of assigning it to the onload event, e.g:

  addEvent(window, 'load', initScroll()); // accidental immediate invokation.
  addEvent(window, 'load', initScroll); // initScroll invoked when
onload event fires.
