I believe you are correct about everything. You must have a window to get
Intuition to send you IDCMP messages. Yes, this is probably why you see
gratuitous tiny windows all the time. One of the better ways to do what you 
want is to do what uShow does. It opens a tiny, invisible window consisting
entirely of its close gadget in the upper left corner of its screen. This
gives you a close gadget for your screen, and a window structure with which
to manage IDCMP messages. If you're not sure how to make it invisible, try
BORDERLESS and BACKDROP in the NewWindow's Flags field.
