What I Did:
1. Opened a Search in a floating window.
2. Searched for prayer in Everything.
3. Dragged a search result from the search panel to the top to open it in a new tab.
What Happened: Logos immediately crashed.
I've been able to replicate several times now.
Mac OS 10.11.3 with Logos 6.9.0.0029

Can anyone else confirm?
