This crash is repeatable:
Steps:
1. Open BWS and enter a greek word (i.e οναι, καθαρισμός, etc) that is also found in the LXX
2. Run the report.
3. Under Textual Searches section, click on LXX to launch the Search - Morph results, using the search parameters shown.

4. Click on "Graph results"
I encountered this repeatable crash when I was trying to figure out how to display the frequency histogram using a non-English bible. I'm not sure how to accomplish this. I now know how to generate the histogram when L5 doesn't crash. Wished the histograms appear in the Textual Searches section as well as in Graph Bible Search Results.

Edit: The crash may also occur when using Logos LXX, Logos LXX ALT, and Lexham LXX bibles - depending on the greek word I think. For example, using the greek word for clean, pure (καθαρός), L5 crashes when using the Lexham LXX Int Swete Alt, but does not crash when using Lexham LXX Int Swete, Lexham LXX Int, and Lexham LXX Alt. Weird.
