I use the KJV 1900 as a main Bible and Logos automatically attaches "The Apocrypha: King James Version" to said module. (Annoying, as it replaces the KJV 1900 in the same tab, instead of opening a new one; yet no real problem there.)
For the KJV 1900, it has cross-references to the Apocrypha. (Again, no problem.)
In a good way, I somehow made the Cambridge Paragraph KJV (AV 1873) to act as the pop-up verse preview. (Another good thing, so the KJV 1900 doesn't just switch to the KJV Apocrypha book in the same tab.)
Yet when I actually click on the Apocryphal verse cross-reference when using the KJV 1900, instead of going to the KJV 1873 tab as that is being previewed, it hangs and then crashes. This happens every time.
In this image, the KJV 1900 is being used, the cursor (invisible here) is hovering over "Wisd. 12:12". And yet if I click on that cross-reference, Logos will always crash (as with any Apocryphal cross-reference, despite the AV 1873 being open in another tab):

This crash problem has to do with the 3 following modules:
