The patch is okay!

The problem is in focus.c co_IntSendActivateMessages:

      /* Send palette messages */
      if (co_IntPostOrSendMessage(hWnd, WM_QUERYNEWPALETTE, 0, 0))
      {
         co_IntPostOrSendMessage(HWND_BROADCAST, WM_PALETTEISCHANGING,
                                 (WPARAM)hWnd, 0);
      }

After the WM_QUERYNEWPALETTE call it make a broadcast call then goes into a
endless loop. So due to many Thread/Window/Class etc changes, things are
running faster than before. UserPostMessage (Wnd == HWND_BROADCAST) may need
more failsafe checks to test thread and window life and that includes
IntWinListChildren and related code through out.
