I am able to easily replicate this crash!
I am working in Colossians 1 and decided I want to extract a small portion of a note from Dake's to incorporate in a user note. I did a "command C" to copy and then placed my cursor in Colossians 1:9, I then did a "command U". The note dialog box came up EMPTY (should have had three entries-Bob's Notes, Sample Notes and Sermon Notes). When I clicked "OK" on the empty dialog box Accordance instantly crashed. I repeated this twice.
I have attached the workspace in use at the time.
