I'm reaching out to see if any other Mac users who have the Theological Journals collection can reproduce the problem I'm having. This problem has been escalated from Tech Support to the developers so I know that Logos is on this. But I'm curious.
There are two resources (there may be more, but I'm aware of two) within the Journals collection that will cause Logos to freeze up and require the Force Quit to get out of the program.
1. Master's Seminary Journal 11:1, "Ephesians 1:3-4 and the Nature of Election"
2. Journal of the Grace Evangelical Society 15:2, "Do Believers Experience the Wrath of God?"
