I think you must trace changead fields - did it was changead after your previously refresh or not when you change the same field in another form. And you can do it only programmatically (writing code for checking all fields). It is complicated when you have many fields in the form.

There is good examples in Rod Paddock and K book: 'Visual FoxPro 6 Enterprise Development'.
