Which brings up another question: do I need the "object" (blue cube)

Not only are they redundant, this is almost certainly your bug.
Objects in a nib are real objects. Therefore you have two of them,
both of the same class. Normally File's Owner is the window controller
and this is the object you should be referring to in your code. The
other object is getting in the way and likely causing problems.
You generally use a blue cube for any other object, such as a separate
subcontroller that your main controller might want to use, but they
definitely won't be the same object - they can't be, as each item in a
nib is a distinct, real object.
