Brian,

Ok, I've attached a demo.  The basic problem is not fundamentally that I
want make the modal window invisible initially, but that I want to make a
substitute for a message box, which has to be responded to before anything
else can done in the program, and I thought it would be nice to center it in
a maximized window (in a general way, independent of the size of someone's
screen); but when I do center it, it "flickers" the *first* time it is
opened in the program, as it first opens in some non-centered place and is
then moved to a centered position.  (If you close it and then re-open it, it
doesn't flicker, apparently because when it is "closed", it is made
invisible, and doesn't get made visible until my "setVisible" true makes it
so, which is *after* it is centered.)

So I figured if I could make it invisible initially, until it was safely
moved to center, no one would ever see it flicker.

Maybe there is some set of "styles" which when or'd will give the
fundamental properties of a modal window, but *not* include "WS_VISIBLE"
that would work with "openWindow"?
