nowhere in this code does a TFormCapture object get assigned to frmcapture.
Note that the type and the handle are different.
the code
> procedure TfrmCapture.btnCaptureClick(Sender: TObject); // Modal form
> begin
> frmcapture.WindowState:=wsMinimized;
> frmcapture.Visible:=false;
should really be
procedure TfrmCapture.btnCaptureClick(Sender: TObject); // Modal form
begin
WindowState:=wsMinimized;
Visible:=false;
NB: there is an implied self. in front of the WindowState

Look in the dfm file and you'll find something like:
Application.CreateForm(TFrmCapture,frmCapture);
remove it if you're creating resources on the fly (the best way IMHO)
You should also remove the
var
frmCapture :TFrmCapture
from the unit containing the TfrmCapture definition. Always use self rather than
the frmCapture handle inside any procedures or functions of TFrmCapture since
your code is then more easily adjusted should you ever want multiple copies of
the form.

He he... the form object created in the dfm file is the one you've minimised but then
it was never shown...
Niggly one to find if you've done this... No debugger is gonig to show you this except
that the pointer value of self and frmcapture will be different showing that there are
in
fact 2 forms...
