Was a five out of five until the last update, now half the pages on the pdf are missing, replaced by completely grey pages. They run fine on adobe, so not a pdf file issue Hi, per your reply: please advise on email address so I can send images, please note I can not send book as it it a paid for commercial item, as such I do not want to commit any copyright infringement to the author. It is happening to every pdf that it is viewing, thanks.
