<li><font size="+1">The problem is making user the buttons are placed correctly
inside the frame.</font></li>
<li><font size="+1">Some user interface toolkits supply a graphical layout tool
to define the placement of buttons, text controls, and other user interface
elements in a frame.</font></li>
<li><font size="+1">Such tools make designing a user interface simple, but the
design tends to be fragile.</font></li>

translated to another language: "Goodbye" to "Auf Wiedersehen")
