Sometimes, with Internet Explorer version 6 each page is shrunk to fit the window, making reading difficult. To see the page at full size and scroll around, hover the mouse cursor over the image until the expand/contract
button appears at bottom right, and then click on it. A similar feature may be available with other browsers.
