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 "snapshot" of it's state at a previous point in time.
</p>
<p class="form-help">
Select one or more transactions below and then click on the "Undo"
button to undo those transactions. Note that even though a transaction
is shown below, you may not be able to undo it if later transactions
modified objects that were modified by a selected transaction.
