Not exactly. The WndProc of the TApplication object intercepts the
WM_ENDSESSION
message and sets FTerminate to true so that the message loop is left after
returning from
this message. The problem is that this will never happen because as soon as
you return
from the WM_ENDSESSION Windows will terminate the app. This is the design as
stated in the Windows docs and so the VCL code will never work. But in my
case
the WM_ENDSESSION message handler is interrupted by Windows before it
returns,
and that is a different story.

Thank's for sharing your experiences.
Regards,
Frank.
