I am using unreal book with or without a bt air turn page turner (doesn't matter). I have a fair amount of data in it. I use the animation for turning pages because it helps me see that the page has been turned. [ The instant turn I find a bit jarring. ] Recently instead of a zip page animation, it puts half the new page at the top followed by a purple bar, and below that is the bottom half of the old page. Then a second or so later, the bottom half of the new page comes in and the purple bar disappears. USUALLY this is OK, because the page is whole by the time I get down to the second half. HOWEVER, it is a problem when I flip to a page that has a coda or something on the bottom half, and I need to see it immediately. Has anyone else seen this? I intend to turn off animation and see if it solves the problem. OK did that and nope. Weirdly enough it only happens on forward turns, not turns back and not hotspot turns. I timed it and it takes over a second to completely update the page. Completely unacceptable for live performing. Help please???
