Default Panes View (On First Time Application Entry)
Version 3.0.0 of the UTB has introduced an option in Tools / Options / General tab to allow the UTB User to define how the Panes screen will display on application start up.
The default pane display settings are:
Always show the Query Builder pane
Always show the Sort and Criteria pane.
The SQL Source pane is not checked and will not appear in the display. It can be turned on in the View / Show SQL Source pane menu option at any time while the UTB session is running but if the application is closed on reopening the SQL Source pane will again not show.
In order to show the SQL source pane at start up, it must be checked 
here.
