#20 Since android upgrade to 4.4 every book displays in italics

Hi....Just upgraded (on my Samsung S4, Android) to Android 4.4.

Opened a book on CR, and I get nothing but italics. Tried a few other books--the same, including the CR manual.

Can't see any way to change this. From the OPTIONS section, I can make it bold or not bold, but no matter the font selected, they are all italic. At the moment, I have it on Times New Roman, size 72 (wish it could go larger!)

Not sure what has happened, but any ideas? (And perchance is there a way to go larger?)
