Sounds like you found the main TApplication window for your executable.
TForm is NOT the top-most main window of a VCL program.  TApplication is.
TApplication has a 0x0 pixel visible window.  That window controls the main
taskbar button for the program, amongst other things.

While searching for windows, you should be taking their class names into
account, so that you can skip past undesirable windows such as
TApplication's.

Actually, it could very well be the case.  The TApplication window is simply
too small to see with the human eye, but the computer still knows about it
and treats it like any other window.

No.
