[Cuis-dev] Flickering with some widgets

[Luciano Notarfrancesco]

Hi Hilaire,
I think this happens because the morphs inside the list are handling
keyboard focus, so when the mouse pointer hovers one of the items the
keyboard focus changes (the list loses the focus and the color changes).
One way to deal with it is to lock the morphs that you use as list items,
just send them the message #lock before adding them to the list. I’m not
sure what’s the best way to do it, did you find a better solution or do you
have other ideas?
