I will just add that I still don’t recommend `OnCloseQuery` for this purpose, for reasons explained in comment in [Where to intercept closing application? - #3 by michalis](https://forum.castle-engine.io/t/where-to-intercept-closing-application/1897/3) 🙂 I know it works in your project, but in general

- `OnCloseQuery` is a way to “ask for confirmation before closing form (e.g. to save some document)”, not “a place to do cleanup”.

- `Stop` is a place to do cleanup, and if you want `Stop` of your view to happen before some `finalization`, then use `Application.MainWindow.Container.View := nil` , as shown in this thread (point 3 above, which I understand the OP followed) or [Where to intercept closing application? - #3 by michalis](https://forum.castle-engine.io/t/where-to-intercept-closing-application/1897/3) .
