Thanks Nicolas. This thread has been enlightening! I did some changes recently, mostly inspired in yours, that improve perfomance and simplify code. 

You can download a fully updated Cuis from https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev . It should be a bit faster.

Thanks, 

Juan Vuletich
