  This application's transactional feature allows you to easily undo changes
  made to the application's settings or data. You can revert the application
  to a &quot;snapshot&quot; of it's state at a previous point in time.
  <P>
  Select one or more transactions below and then click on the &quot;Undo&quot;
  button to undo the transactions.  Note that even though a transaction
  is shown below, you will not be able to undo it if later transactions
  modified objects that were modified by the transaction.
