My code:

void __fastcall TFormShowWindow::CreateParams(TCreateParams &Params)
{
  TForm::CreateParams(Params);
  Params.ExStyle |= WS_EX_APPWINDOW;
}

void __fastcall TFormShowWindow::NewWindowProc(TMessage &Msg)
{
  switch(Msg.Msg)
  {
    case WM_EXITSIZEMOVE:
         if (Parent == parent)
         {
           BorderStyle = bsSizeable;
           Parent = NULL;
           Top  = ptCurrent.y;
           Left = ptCurrent.x;
           Width  = Width - 20;
           Height = Height - 20;
         }
         else
         {
             BorderStyle = bsToolWindow;
             Top    = parent->ClientRect.Top;
             Left   = parent->ClientRect.Left;
             Width  = parent->ClientRect.Right;
             Height = parent->ClientRect.Bottom;
             Parent = parent;
         }
     break;
  }
}

The problem is that when i set Parent to NULL, the taskbar is updated but 
the
ALT-TAB selection i can't find it, and the main form can't raise to the top.

Thanks for Your help

Ciao
