You can call:        -[NSWindowController loadWindow]

But I'm not sure if that's really what you should be doing - see my 
comments below.

No, this checkbox controls something else at a lower level, something 
you shouldn't mess with.
I have to say, I'm not even sure why we have a checkbox for this in 
IB...

If I read this correctly, you use the controls in your window as model 
objects to store preferences that are accessed by other parts of your 
application? If so, I'd suggest that this is a design flaw that you 
should fix. The view objects in your application should not double as 
model objects - See: The MVC design pattern.
