Indy and the Last Crusade book of maps help

[omaer94]

I'm using ScummVM Latest version and I have Indy and the Last Crusade In the game I picked up the book of maps in the library and whenever I look at it, I can only look at this passage "Deep beneath the city lie the paths to the tomb" Can anyone tell me how to turn the page of the book. I tried so many buttons but nothing happens.

You can't turn the pages of the books.
