I believe you need to use view-local coordinates if the window is
composited
and port-local coordinates if not.


Do you mean I have to convert the mouse location to view-local before
passing it to kEventWindowCursorChange?


Correct. This is what I do (and it works):

        HIRect    frame;

        HIViewGetFrame( view, &frame );

        inLocalMouseLoc.h -= frame.origin.x;
        inLocalMouseLoc.v -= frame.origin.y;

HandleControlSetCursor( view, inLocalMouseLoc,... );

After thinking about it some more, this doesn't completely make sense. What would happen if the frame origin is out of QuickDraw coordinate space? Doesn't it all fall apart then?
