I placed an ad in the ad terminal, and it was working well. There were three pages to the ad. Later, there was another ad placed, and after that, the first page of my ad stopped displaying. WHen my ad enters the rotation, it begins on page two. My guess is that because the second ad has a diagonal transition effect, when my ad comes up for display the transition effect carries over to my ad, and the first page does display, but with the previous diagonal effect, and it scrolls by off the edge of the screen where it cannot be seen. Instead, during the time when the first page SHOULD be seen, the screen is black.
