Can you show an example for that using current gtwin.c code?

We're already handling these events, so if doable, it should 
be implemented here:
---
static BOOL WINAPI hb_gt_win_CtrlHandler( DWORD dwCtrlType )
{
   BOOL bHandled;

   HB_TRACE(HB_TR_DEBUG, ("hb_gt_win_CtrlHandler(%lu)", ( HB_ULONG ) dwCtrlType));

   switch( dwCtrlType )
   {
      case CTRL_C_EVENT:
         bHandled = FALSE;
         break;

      case CTRL_CLOSE_EVENT:
      case CTRL_BREAK_EVENT:
         s_bBreak = HB_TRUE;
         bHandled = TRUE;
         break;

      case CTRL_LOGOFF_EVENT:
      case CTRL_SHUTDOWN_EVENT:
      default:
         bHandled = FALSE;
   }

   return bHandled;
}
