On page http://minnow.cc.gatech.edu/squeak/52 , Hannes Hirzel has a very 
good and very simple example of the layout of Morphs as follows:
------------------------------
m := RectangleMorph new.
m layoutPolicy: TableLayout new.
m listDirection: #leftToRight. "If you omit this expression you get the 
default "
"m listDirection: #topToBottom."
m hResizing: #shrinkWrap.
m vResizing: #shrinkWrap.

m addMorph: (EllipseMorph new extent: 40 at 40; color: Color red).
m addMorph: (EllipseMorph new extent: 50 at 50; color: Color yellow).
m addMorph: (EllipseMorph new extent: 60 at 60; color: Color green).
m addMorph: (EllipseMorph new extent: 70 at 70; color: Color blue).
m openInWorld.


You can change anytime between:

m listDirection: #leftToRight.

and

m listDirection: #topToBottom.
------------------------------------

It works! It's simple, it's elegant, it's beautiful.

Now continue with one of these at the time:

m listDirection: #leftToRight.
m listDirection: #topToBottom.
m listDirection: #leftToRight.

It still works. Now do
m listDirection: #topToBottom.
m listDirection: #rightToLeft.

WE NOW HAVE THREE CIRCLES STACKED ON TOP OF EACH ORDER WITHIN A SQUARE!!!

I must be missing something. But what?

In confusion
