Either way, instead of going back & forth on this, why don’t you try
implementing an NSView subclass without hitTest returning self and see if that

Thanks.
It is always worth trying something trivial regardless of arguments.
I implemented hitTest to return self in my NSView subclass. It made no
difference.
After that, I tried having hitTest call the super method to see what it
returned. For the simpler version of my window nib with only one view the super
method was returning self. For the more complex version of the window nib with
3 views (of the same class), my NSView subclass's hitTest got called 4 times. In
2 cases the super method returned self; in 2 other cases the super method
returned 0. I did not look at further details but it seems likely that the
default implementation actually checks whether the location is in the view and
returns 0 otherwise.
Because of the other behavior I reported re Window resizing and splitter
dragging not working once the window is frontmost, I implemented
acceptsFirstMouse, returning YES.
The result is that my view now receives mouseDown in the same circumstances in
which the other functions work: when the window is not frontmost.
So it seems somehow the window is being disabled once it is brought to front,
either by a click or programmatically via makeKeyAndOrderFront.
Thanks to all for the fantastic help so far, on the weekend no less. I might
have been utterly stuck for a long time without it. I'm still stuck but I have
a couple good things to try.
