To reproduce:
- Start DI App
- Click File->Exit
> Crash
This kind of problem has cropped up many times. This might be something similar to T2520 , T2922 , T6986 or any other of those numerous bugs with a similar subject.
While this might possibly be a non-DI caused problem I'm filing this under DI, because currently the DI App crashes when doing this while the Sandbox App does not.
