Answer. Modern Web browsers will "cache" (or keep a local copy of) Web pages in order to make browsing faster. It is likely that you are looking at an old copy of the page that's actually on your computer rather than in Blackboard. You can force your browser to update the page from the Web by clicking the "Reload" or "Refresh" button at the top of the screen. You can also force Internet Explorer to reload the page by holding down the Control key and tapping "R."
