Just supress SC_KEYMENU, SC_MOUSEMENU system command type of
WM_SYSCOMMAND message. They are responsible for sys menu poping out.

Assume you want to do this for Form2:


type
  TForm2 = class(TForm)
// .....
  private
    { Private declarations }
     procedure WMSysCommand( var msg: TWMSysCommand ); message WM_SYSCOMMAND;
// .....


implementation


// .....

procedure TForm2.WMSysCommand(var msg: TWMSysCommand);
begin
  case msg.CmdType and $FFF0 of
    SC_KEYMENU, SC_MOUSEMENU: begin
      msg.result := 0; // Eat this message
      Exit;
    end
  end;
  inherited;
end;

If I understood correctly you should write

Procedure TForm1.DestroySysMenu;
var mnu: HMNU;
begin
  mnu := GetSystemMenu(Handle, True);
  DestroyMenu(mnu);
end;
