iBooks Author size issue when widget plays automatically

What I would like to achieve in iBooks Author is a full page Hype Widget that plays automatically. I have set the document up as a preset 1024 X 768 in Hype but it doesn’t quite display full page when I preview on the iPad. If I disable autoplay it plays full page perfectly. Does anyone know what’s going wrong?

A Book about Hype notes that this is a bug in iBooks Author.
