[Cuis] How to center a submorph in its owner morph?

[H. Hirzel]

Hello

I currently encounter some problems with Morph layout and I would like
to ask for help.

The code [1]  works fine in Cuis 4.1.

A slightly adapted version (just below) in Cuis 4.1 gives the morph as
shown in file
Cuis4.1-green-LayoutMorph-with-red-BorderedMorph

| row b |
row := LayoutMorph newRow.
b := BorderedRectMorph new color: Color red.
b morphExtent: 120 at 120.
row
    color: Color green;
    addMorph: b.
row padding: #center.
row morphExtent:  200 @ 200.
row morphPosition: 150 at 130.
row openInWorld.
b inspect

However the extent of morph b is wrong. After setting it manually in
the inspector it looks as shown in picture 'Cuis4.1-green-red120.png'.
This means setting the extent works here.

In Cuis 4.2 the result of the same code looks as shown in the picture
'Cuis4.2-initial.jpeg'.

And it refuses to resize the morph b even if done manually.

Any suggestions to help to fix these bugs are welcome.

Regards
Hannes
