In the vertical display, I cache two pages in each direction. That means you should be able to see three pages at a time on the screen at any time. If there is an easy and consistent way to produce this problem, please export the song to a .msf file so that I can test with the same thing you are using. I just tested this using file small pages of varying sizes and I always see at least three songs on the screen at all times - I never saw a black page.

Thanks,
Mike
