There's this little glitch that has bitten me more than once: the 
closefield message isn't always sent if you remove focus from a field by 
clicking a button. To get the closefield message, you have to click on 
the card to remove the focus first, then click the button.

I had to script a line in my buttons to send an artificial closefield 
message to the field. This wouldn't work for you if you really need 
closefield to only trigger when a field has changed.

I think if you set the autohilite of all buttons to false, you'll get 
the normal messaging behavior; it is only when autohilite is true that 
the button ignores a change in focus and the field messages aren't sent.
