I was executing it from a WorkSpace. And you are very right I didn't notice
the difference between creating an
object inside the island and off.

"code to assign self to be the Island"
> self activeSpace future addChild: (self activeIsland future new: TCube)


I guess what it comes down to is I should let the Island create the TCube
itself by sending it a future message.

I originally wanted to play with TVehicle and friends, but i couldn''t get
anything to work, so i scaled down to a cube.
But now i understand i missed a layer ...

Thanks very much for clearing this up.
