Copy-paste from original mail:
anchor constraints: they do not play well with layouts and animations. Try the
code below (adapted from the example to use the layout and animation of LRP )
and you will see that the circles keep spinning around, they never stop. I
think it would be better for them to stop ;-)

v := RTView new.
lbls := RTLabel new elementsOn: #(#First #Second).
es := RTEllipse new
size: 30;
borderColor: Color black;
elementsOn: #(#source #dest).

addAll: lbls;
addAll: es.
