Once I select a topic (for example Troubleshooting) there is no way to
go back to the main section of Troubleshooting so that I can select a
different option.  In order to do it I must select a different topic
such as Settings and then I can go back into Troubleshooting.  We would
like to be able to go back to the subject main menu even if it is
already selected
