A Single-Right-Click of the Projector Patrol Sentry system tray icon displays the Sentry menus:
The Sentry menu can be customized to hide the Service menu. This can be useful if you want to make it difficult but not impossible, (see note) for a user to defeat the Sentry by exiting the application.
You can also toggle the visibility of the "Configure" menu by holding the [Ctrl]+[Shift] keys and simultaneously clicking on the Sentry system tray icon.
Note: Sentry will always honor a termination request received from the Windows Task Manager.
