Hi,

I'm not sure it is but I think I have found a bug where elements share the same instance of a shape.

Here an example:

view := RTView new.

els := (RTBox new size: 20) elementsOn: (1 to: 10).
view addAll: els.

els do: [ :e |
e on: TRMouseClick do: [ :event |
e shape color: Color random. e update. els atRandom update. view signalUpdate ] 
].

RTHorizontalLineLayout on: els.
view open

It should only change the color of one element but it doesn't.
So I don't know if it is wanted or not.
