In Internet Explorer, the browser refreshes pages when the "Forward and Back" buttons are used through the navigation history stack and always pulled from the cache. If there is corruption in the cache for any reason, the back button may not work. To work around this problem, use the History bar to return to a Web page previously visited. To do so, click History on the toolbar, and then click the site wanted. Microsoft has confirmed this is a problem in Internet Explorer 5 which may be corrected by installing a newer version or perhaps updating to SP2.
