It might be because Apple's way of alloc-ing the field editor on the spot may
not be such a good idea. If I remember correctly, it didn't work for me. That
may be the cause of your problem.
So my suggestion is: Try making an instance variable for the NSTextView, and
create it once in -init or -awakeFromNib in your window delegate. And then
return that one instance from the -windowWillReturnFieldEditor method.
