[Cuis-dev] Flickering with some widgets

[Juan Vuletich]

Exactly as Luciano says. If the morphs in the list handle keyboard 
focus, they get it, meaning the list loses it. A quick test is to define 
this in BorderedBoxMorph:

handlesKeyboardFocus
     ^(self class == BorderedBoxMorph) not

So, it is a matter of using morphs that don't take keyboard focus.

HTH,
