Media List
These settings pertain to Images List, Audio List, and Video List states:
Return to start after inactivity: Check the Yes box to have Media List states play from the beginning upon reentry after a designated period of inactivity. In this case, "inactivity" is defined as any time not spent within the Media List state.
Inactivity timeout (seconds): Specify the period of inactivity before Media List states restart. If the presentation spends longer than this amount of time outside the Media List, it will play from the beginning of the list upon reentry.
