Here is a repeatable crash on my system:
1. Using the NKJV right click on the word "God" in Titus 3:4.
2. Using the Lemma, select Bible word Study.
3. Logos4 crashes
Here is the log file:
7674.Logos4.zip
In the previous version there was a bug in the Word Study Guide that I had reported and others had confirmed (no one from Logos), that affected words that were used several times in the Bible (at least over 250 - especially over 1000 times).
It is documented part way down the page here:

This bug still exists in the Beta.
