I suspect the issue is that since the "anchor" is the origin point, which is bottom-left, that resizing top/down is the issue since that would be the only time that the window "moves" as a result. Depending on whether you want the child window to "snap" into place or to live resize, OTOH, I would keep the *top*/right coordinate point of the child window in the parent window's coordinate space, and then in -windowDidResize: or windowWillResize:toSize: (for snap or live consecutively), or both, perform a delta to see if that top/right point has changed, and then change the relative position of the child window. Sounds pretty easy to me... HTH, Keary Suska Esoteritech, Inc.
