As soon as you move cursor with the mouse or touch any key on the keyboard, slideshow stops. The slideshow switches to preview when you move the mouse pointer. Slideshow mode stops when you move the mouse pointer and monitoring continues on the last database and you can manually switch between connected databases.
This was implemented by design in the 4.5.2 version.
This functionality changed in the latest version of Spotlight on Oracle (4.5.2). It now appears to work according to what the Slideshow Option dialog states. Refer below. The reason this was changed is, it was seen as a more natural workflow for the user to terminate the Slideshow mode by pressing the keyboard or moving the mouse when they saw something of interest on the Home Page of one of the connections. It was seen as cumbersome to go to the " View | Slideshow " menu item to turn this mode off.
