I make extensive use of the Keynote widget when creating my books. On occasion after previewing the book on my iPad, I launch the widget and the screen comes up blank. The only way to get it back to normal is to quit iBooks and restart the app. Then all widgets are back to normal...until it eventually happens again. If one widget goes blank, all widgets in the book go blank. Any suggetions?
When I export the presentation from keynote, I export it in low quality and then drag the folder into iBooks Author. At which point I make it full screen only. Any help would be greatly appreciated as so far this is the only fallback I'm having with iBooks Author.
