Hi Paul,

(without having opened your model file:)

I first had similar problem with the layouts. When you want a container
to layout its children along e.g. a GridLayout, then you need to do two
things (some users - as me - omitted the second one ...):

1. Add a 'GridLayout' to the *container* (i.e. the RoundedRuleFigure)
2. Add a 'GridLayoutData' to each of the *children*

Note that you can replace 'GridLayout' and 'GridLayoutData' by e.g.
'FlowLayout' and 'FlowLayoutData'.

Regards,

Martin
