Developer's Notes: Note the use of dynamic properties of IE 5 inside the two <div> tags below. We used dynamic properties to ensure that the divs (which make up the crosshair) always expands to the width/height of the viewable browser window, even when the surfer resizes the window. IE 4 and NS 4 do NOT support dynamic properties, so we had to write code (located at bottom) that manually detects when the surfer using these browsers resizes the window, and reloads the page whenever that happens.
