Yes, I must have not been clear. Since now it's implemented as a 
sheet, it's no problem. Initially I was using a modal panel, and 
running a panel modally you seem to have to grab user input after you 
send NSApp stopModal. But thanks to everyone I now have it all figured 
out as a sheet now, and I think I'm actually MVC compliant with the 
way I did it.

And thanks for the tip on the tetris source - I'll check it out.

  The statement that worries me is "The thing I was missing is that I could
still grab the text field's value after it was off the screen."

  It is a bad idea to store Model data such as the name that goes 
with a high score in a View.  You should be able to release a dialog 
window and all of its contents at any time without any affect on the 
Model.

  Incidentally, "Cocoa Programming" uses and fully implements a 
Tetris game as an example of how to apply the Model/View/Controller 
pattern.  Doubly incidentally, "Cocoa Programming" also uses a high 
score table as an example of master-detail interfaces with table views.
