How do i make my start menu and my IE8 menu appear and reappear?

a couple days ago i accidentally pressed something and my IE8 screen got big, because my IE8 menu and my start menu disappeared and every time i went to the top or the bottom of the screen they would reappear|||To maximize website viewing, the File menu may be hidden by default. Most menu options can be accessed from the toolbar. You can make the Menu Bar (File, Edit, View, Etc.) appear by clicking the Tools menu, located near the upper right of the screen, and then Toolbars and then Menu Bar.|||Right click on a blank area of the Start Menu Bar, Choose Properties, and ckick on the Auto-Hide option to change its behavior.
