Hi Branimir and thanks for the suggestion
I tried what you suggested and its works fine for detecting when the User
closes the app. The WM_CLOSE is received directly after MainForm_Closing gets
executed.
I still am in the situation where I cannot find a way of determining when
the App is closed via Shutdown.
