Chid window within console window

[Gato]

Child window of console application. When WriteConsole(), their contents are overwritten. The only way I found of avoid this was to create it with GetDesktopWindow() as parent and, for always seeing it, use HWND_TOPMOST. Very, very, very ugly and nasty. Child window, of course, with WS_CLIPCHILDEN and WS_CLIPSIBLINGS.
How can I avoid this without these bad methods?
Thanks
