    that requires immediate input from the user.</font></li>
  <li><font size="+1">Because the user can do nothing else except fill or cancel 
    the dialog, it can be a burden.</font></li>
  <li><font size="+1">Nevertheless, modal dialog boxes are necessary whenever 
    a program simply cannot proceed with user intervention.</font></li>
