I am not disputing the veracity of the release notes!
The troublesome aspect is that I cannot override this new behaviour.
The view will not seemingly permit its nextResponder to be diverted from the NSViewController.
I am not aware of anywhere else in app kit where this occurs nor can I really understand why this sticky responder behaviour has been adopted.
Normally I can assign the nextResponder as I see fit.
I had hoped that whoever coded this new behaviour might chip in…
Thanks for the reply.
