First, sorry about my last post with the RE:Contents of ... title.

Anyhow, I figured out what was wrong. Seems you need to call
[self.view addSubview:picker] to hook up the picker to the view
controller. I am doing that in my viewDidLoad method.

The text view will not be sized any smaller than its minimum size,

Your application instantiates a PDFPage object by asking for one from

I am really a total newbie (3 or 4 days) with IB, so I have NO
confidence that I can tell what is a bug yet. I barely understand
what I am doing as yet.
However, I should have done the IB run mode thing. I did not think
of that. I just looked at it and it looks correct (no extra item). Go
(color default = 4, size default = 3).
I guess I could have a dictionary for each popup, but that seems
clunky. I see there is something called Bindings for menu/popup
items, is that a way to go? (I am trying not to put the info in the
NIB, I would prefer code, where I can see it.)
