I am noticing that many of my books have large blank sections in them. The text of the book will suddenly stop, and I will have to scroll down through blank white space before the text picks up again (where it left off). I have noticed this happening in the BHS, several Word Biblical Commentaries, and van der Merwe's Biblical Hebrew Reference Grammar.
Background, I recently transferred my logos 4 from an XP machine to a Windows 7 machine. I performed a software update several days ago but this did not fix the problem.
