The Smalltalk as documented in Adele's books is a very old version. A  
lot has changed. Forms, for example, have been extended to support  
color. And the interface
for instance creation has been changed, as you have seen.

In general, the goal of Squeak was (should be, used to be) not to re- 
create a 100% Smalltalk-80 compatible system, but to transcend  
Smalltalk... sadly not much has been
archieved, and the sytem even contains a lot of the old MVC code that  
is not used anymore (and slightly broken in many cases, as code not  
used rots). The Form editor,
for example, seems to only work in MVC and not Morphic.
