I have Logos 5 and a space dedicated to the study of Zechariah. I have a lot of books (20 plus) and lots of windows (6) in that space. But once I open "An Exegetical Commentary; Haggai, Zechariah, Malachi by Eugene H. Merrill, the program crashes (not instantly) within five minutes. Removing Merrill, and the work space is free of problems, as are my other work spaces (Romans and 2 Corinthians). It took me a long time to find which book was the problem. I would like to find a fix, because I want to use that book. I may have to get my copy off my book shelf!!!
