"memory hoarding" problem [Delphi, Windows]

jarek ©   (2009-03-03 17:50:00) 

Hi all,
I have problem with this code:
program FormsTest;

uses
 KOL;

type
 PForm1 = ^TForm1;
 TForm1 = object(TObj)
 Form: PControl;
public
 procedure FrmClick(Sender: PObj);
end;

var
 Form1: PForm1;

procedure NewForm1(var Result: PForm1; AParent: PControl);
begin
 New(Result,Create);
 with Result^ do
 begin
   Form := NewForm(AParent,'Form1').SetSize(320,240);
   Form.OnFormClick := FrmClick;
 end;
end;

procedure TForm1.FrmClick(Sender: PObj);
var
 NewForm: PForm1;
begin
 NewForm1(NewForm,Applet);
 NewForm.Form.Show;
 NewForm.Free;
end;

begin
 Applet := NewApplet('Forms Test');
 NewForm1(Form1,Applet);
 Run(Applet);
end.
Application takes  after start 3108 kB of memory.
When I click on the form, new window opens and application takes more of memory. If I close this new window, the usage of RAM not changes.
If I open 100 new windows, application takes 3376 kB of RAM. If I close all new windows, application still takes 3376 kB of RAM.
Can anybody help me?
Thanks. jarek

Also make use of
SetProcessWorkingSetSize(GetCurrentProcess,Cardinal(-1),Cardinal(-1));
at convenient places, such as after freeing form.

in NewForm1
Form := NewForm( ...
Form.Add2AutoFree(Result);
