How to repeat:
When closing the SQL Editor tab, upon returning to the home screen, I receive an error message. I clicked Report Bug this time. Upon clicking close, Windows displays a crash message and I have to click Close the Program.

This does not happen every single time, only on occasion. I cannot find any sort of pattern.
