Getting dirty

[Ken Ray]

Ray,

Actually from my perspective, MC is pretty on-target with SuperCard and
HyperCard: 'openField' is triggered when the field gets the focus (it's
clicked in or tabbed to), 'leaveField' is triggered when the field loses the
focus and no changes to the field have been made, and 'closeField' is
triggered when the field loses focus and there *have* been changes to the
field. So trap 'closeField' and you know when a field is dirty.
