Why doesn't    - initFrame   see outlets that the rest of its object sees, such  
as Forms?

E.g.,

  x = [aForm floatValueAt:0];

does not give an error message, but, within initFrame, it does not assign x  
either.  The same statement in other methods of the same object do assign x  
properly.

Any insights?

Thanks in advance,

If you're using an IB-generated view, at the point when -initFrame is called
within the view the form isn't necessarily instantiated yet.  if you use
an NXApp delegate you can get at the object after everything has been
instantiated by using the "-appDidInit:sender" delegate method.

you might want to use gsb to check at the point you're trying to manipulate 
the form and see if it has any value.  If it's not instantiated, it will have
no value and any messages sent to it get lost in the ether.
