If the window has been moved the programmer is probably
trying to center or position it. Thus we set the callback

Without moving or centering the dlg, it will just stay
in the upper left of the frame, it does not center
automatically.. One additional note, when the hook is
enabled, the PLACES BAR in the dlg (shown on later versions
of windows (2000 and XP) will automatically be turned off
according to the MSDN docs. This is normal. If the
programmer needs the PLACES BAR (left side of dlg) they
just shouldn't move or center the dlg.
