That is how it is implemented. It is set to ActiveControl
unless ActiveControl is Nil or a TCustomForm.
  if (FActiveControl<>nil) and not (FActiveControl is TCustomForm) then
    FLastActiveControl := FActiveControl;

I did not know about LastActiveControl. What is the use of it? TScreen
class seems to have it, too.
Anyway, you can easily keep track of the previous ActiveControl in your
code yourself.
