You already found #stepAt: . In any case, the "message names" tool is 
your friend.

Please, steps to reproduce.

Well, until the morph is inside some owner, its coordinates are 
meaningless. This is different from Squeak, I know. And it might require 
a bit more of thought. I had to fix many places where coordinates were 
set before adding the morph to some owner...

If you can send me an image with preloaded code, or rather specific 
instructions to build one, I'd like to think about this together with 
you. It is quite likely that we tweak something or add some helpers to 
Cuis base.

Bug reports are most welcome. But (as in 3) if the problem is that you 
don't find the "obvious" way to do something, then working together on 
the code will most likely give all us better results.
