<p>Though KDE is a very stable desktop environment, programs may
occasionally freeze or crash, particularly if you are running the
development version of a program, or a program made by a
third-party. In this case, you can forcibly kill the program if need
be.</p>
<p>Pressing <b>Ctrl+Alt+Esc</b> will bring up the skull-and-crossbones
cursor, and once you click on a window with it the program will be
automatically killed. Note, however, that this is an untidy way of
shutting down the program which may result in data being lost, and
some partner processes may still remain running. This should only be
used as a last resort.</p>
