I was running into that too, Mike, as I believe other high volume users were also. After refreshing the screen a few times as you did, I eventually got a red message saying something like, 'Sorry, we are out of new movies to evaluate, please try back soon.' I don't know as that's connected with the buttons disappearing, but we've seen things go wonky before when running out of movies. Anyway, you are not alone. Mike C.
