I develop an MDI program.
In each MDI window, i have pointers.
When I open and close a lot of window, my program fail.
What is the good code ?

  PArrayInteger = ^TArrayInteger;
  TArrayInteger = array[1..1] of integer;
  TMyMWindow = object(TWindow)
    Tab = PArrayInteger;
    constructor Init(...);
    destructor  Done;
  end;

  TMyWindow.Init(...)
  begin
    TWindow.Init(...);
    GetMem(Tab, 22*sizeof(Integer));
  end;

  TMyWindow.Done;  
  begin
  ---> TWindow.Done;
       FreeMem(Tab, 22*sizeof(Integer));
  OR
  ---> FreeMem(Tab, 22*sizeof(Integer));
       TWindow.Done;
  end;
