cjack - I'm using an older iPad, about 2 yrs old (iPad 2?), running the latest iOS 7.1. But when I posted that note I was one iOS operating system version earlier. I believe, from other posts on this thread, that Lionel has fixed the bug causing crashes during track editing; they've posted a new version of LCS since then, but I haven't done thorough checkout of the latest LCS.
