If absolutely have to resume the paused video on the base layer after closing a side-layer there's a workaround. First, setup a number variable, let's call it ChangeFlag. Add a trigger on the baseline: if ChangeFlag changes, play the video. Now, on the side-layer, before you close it, you need to adjust the ChangeFlag variable by adding one. Using a Storyline action (adjust variable) will not work because the baseline will not detect the change. The only way the baseline will detect the ChangeFlag change is if you can change that AFTER the sidelayer closed. How you can do that is put this JavaScript trigger on the sidelayer: player=GetPlayer(); setTimeout(function(){ player.SetVar("ChangeFlag",player.GetVar("ChangeFlag")+1); }, 500); This will add 1 to the ChangeFlag variable half a second after you're closing the sidelayer. By then, you're on the baselayer, and so, the baselayer picks up the trigger. You can play around the number to make sure the sidelayer is closed but the user doesn't have to wait long (time is in milliseconds). Again, use this only you absolutely need to.
