Crash after highlighting a portion of text

[ssel]

I have had this bug for some time. I have just upgraded to the latest 13.3.0, and can confirm that this bug still exist.

So, whenever I use my mouse to highlight a portion of text (by clicking and dragging my mouse over certain text), and then if I click elsewhere, Accordance will crash. 
Although this doesn't happen 100% of the time, but I would say it happens regularly, 60-70% of the time.
