autoHilite and focus (following Jacque's solution)

[Slava Paperno]

Thanks, Ken--but I do want traversalOn to be true: that's the natural
behavior of a search field and the Find button:  type your target, then 

--click Find or
--press Enter or
--press Tab to focus on the Find button, then press Enter

That's why I have, at the bottom of the Find button's mouseUp script, this
command:

focus on field "SearchTarget" of this card

That command is followed, but only for a moment; the next moment the focus
jumps to the card itself. That's the part I'm struggling with. Why wouldn't
the field retain the focus if it is unlocked and its traversalOn is true?

I'm also trying to understand the logic of LC behavior so next time I don't
have to ask the list: you say "when the focus is in the field and you go to
click the button, the focus is shifting automatically to the button you
clicked because the "traversalOn" property is "true".  That's puzzling. I
would think that when you click a button, the focus shifts to it no matter
what (unless the button is disabled). Otherwise every button with a false
"traversalOn" property would be unclickable... no?

Gratefully,

Slava
