I don't know about Gorm, but the current behaviour of hitTest: is right -
hitTest: is used when you do a mouse down on a window, to determine the
view which should manage the mouse down.

If we override hitTest: in NSBrowser etc, then clicking with the mouse
inside a NSBrowser wouldn't work any longer (eg, if you click on a browser
scrollbar, you want the scrollbar to get the mouse down! not the browser).

That for the part I know of.

If gorm is using hitTest: to determine the view to connect to, and if this
is not the correct behaviour (I don't know), then it's gorm which needs
fixing :-) probably if the view returned by hitTest: is not one of the
objects managed by Gorm, Gorm should go up to the superview, and to the
superview's superview etc till it gets to a view which is managed by Gorm,
and then connect to that one.
