User remarked on "goofy" behavior of "set" checkbox. Turns out, he was
filling in a value, and then clicked on the "set" checkbox. As a result,
the checkbox was "off" ... why? onchange is triggered only after the field
lost focus - and it did so, because the user clicked on the "set" box.
OnFocus might be a little wasteful, but less goofy.
