I had to put this in the Logos 5 beta forum as Logos 5 is all I am running now, and I am not sure if it's a Logos 5 problem or something else...
I have a Latin text Personal Book, the book is compiled with language set to Latin, and I verified it in my Library view. But when I right click on a Latin word to look it up, my Dictionary of Latin Forms is not an option on the context menu left-side as it is with Logos resources. Is this a bug, something I have done wrong, or a capability not supported in Personal Books?
