I've exported my book for web app multi device and loaded in up on the ipad by hosting the html files on a local location from my computer. for the most part things are working properly, but one serious game breaker is when you tap on an image to expand it, there is no way to close that image. Tapping, dragging, or anything has no effect so you have to close out the book.
Images are set Mark as thumbnail with the Open Thumbnails in Lightbox option set on export. any ideas of how to solve this?
