Proofing connection has been inactive
I'm trying to preview a book in iBooks on my iPad. iPad connected via my keyboard, iBooks open, iBooks Author (v1.1). I'm getting a window pop-up daying 'The proofing connection has been inactive for a while' Cancel or Continue. Continue two or three times no help. Cancel left a ghost book 'Unkown Title' - 'Unkown Author' on my book shelf (which I can't delete). Tried again connected via the USB on the front of the computer (Mac Pro). Some problem.
I have quite a few HTML/JS widgets in this book. Exporting to iBook, uploading to my server and downloading via Safari > iBooks works.
Any suggestions? Thanks.
