I think you guys have done a great job!! 

Thank you.

Joe.

Hi Bert,

I downloaded Squeak 5.0.  Seems to work well.  But I have a few issues:

1.  How do I make the system font bigger?

2.  How do I make the flaps disappear? 

Sincerely,

Joe.

That would be one simple way to do it, yes.

OTOH if you're happy with 4.3 there is no need to upgrade - just add the
methods you need to your image.

4.3

What is the procedure for upgrading?  Should I file-out the classes, download 
the new version and then file-in?

Sincerely,

Joe.

I meant a method category (a.k.a. protocol). Right-click in Array's method
categories list and add a new category named *books. Then select it and put
your methods there. You can also use drag-and-drop to move a method to the
right category.

Bert,

I don’t have these methods.  I get an error.  See attached:

Bert, 

I am not sure how to do this.  My project is called Books.  Is this what you 
mean?

Object subclass: #Array
instanceVariableNames: ''
classVariableNames: ''
poolDictionaries: ''
category: ‘*Books’


Sincerely,

Joe.


PS.  Thanks for the bit about the join methods and the changes.  :-)
