Once you click the Start pushbutton, the Wackers will come up and start running.   You will not be able to re-enter start information until the Wackers have completed (press the Stop pushbutton to force the Wackers to stop).  You will be able to see the progress of the Wackers on the main listbox.  If you have turned on "Log Return Information", you can click on a entry in the list to see the information loaded by the Wacker.
