Thanks Jamie for looking at this. I've had no scrolling timeline on at least 3 different computers. The fact that it is appearing on all of your computers gives me hope. I would be delighted to find out that it's something on my end. As for your questions, the screen does scroll horizontally, but there's no timeline. Basically everything works except the timeline.
With the songs set to 'wait for keypress'. First song plays perfectly with timeline moving along to the end of the song. Second song when I hit the spacebar, I momentarily see the third song WITH a scrolling timeline, then it switches back to the second song with no visible scrolling timeline and plays to the end invisible. Same behavior for each consecutive song through the second to last song. The last song plays perfectly WITH a timeline.
Aside from this annoyance, the playlist has been working well. I've even used it in a live situation running critical cues since this last release. My tech guy loved how snappy it was, although he freaked out a couple of times without the familiar timeline (thinking it crashed) and then remembered.
