Thank you, Ken. Yes, your explanation -- that the NSInvocation
retains them as instance variables -- makes more sense than mine.
I submitted Document Feedback that Apple make clear what they mean by
"retain" in this method.

It is an inspector panel. One panel for many documents. The panel is

This is a crucial piece of information which changes the nature of the

Hi Alexander,
If your object is always the First Responder, that would account for its focus

There's a lot of good information available, but you have to look around a bit
to find it.
Googling for - cocoa draw focus ring - shows some good results.

I left out a crucial bit of information not realizing it was crucial.
I was using the NSURLConnection synchronous request every 4 seconds on
the main thread. I noticed that in some circumstances I had a fairly
regular lag spike. Almost timed to exactly 4 seconds, the time span of
my ticker.

Please follow these simple steps to make a very simple test app that

I programmatically create a NSCollectionView and set my own prototype view

other subviews, for example I have a XXView object containing an NSTextView

I may be wrong, but my understanding was that this sets up some sort
