I don't know exactly what you're doing. It seems that you create a
window sometime during execution. If you use any VCL then there is the
VCL to do this for you (yes this hidden window for the Application
object). That immediately takes focus to your app and even prevents
you to preserve the old Active window with the first statement in your
Project-source (funny it is somewhere in the initialization code for
this VCL-source). You can turn this behaviour off by doing this:
Create a new unit which looks like:
unit first;
interface
implementation
initialization
IsLibrary := True;
end.
and make this the first used unit in your project source. This makes
the VCL think it is in a DLL and so there is no auto-created window.
You have to test, if there are side-effects.
Hope this helps
