[Cuis-dev] Mouse Focus

[Hilaire Fernandes]

Good idea to inspect the hand!

What I am observing is that, when I press my morph, the inspector shows 
it gets the focus. Once I release the button, the focus is lost.

So I try with button1up event. This time the focus sticks to my morph, 
but then with the mouse I can't select any other morph. I need to show 
the halo of any morph, so my morph looses the focus, then I can select 
any morph then.

There is likely something I don't understand. Likely what I want to use 
is the keyboard focus.

Joined is the code.

Thanks

Hilaire
