I can't speak for WinNT, as I don't have it available, but on Win98,
using HWD_MESSAGE as the parent window to CreateWindowEx() appears to
work fine (despite what MSDN says).  Using it I end up with a window
that is a child of a hidden system window.  The window is not top
level, not visible, and I can't make it receive a broadcast message.

As soon as I can get back in front of a Win2K box I'll look to see if
the implementation looks the same there.
