Unfortunately, I don't know of anything that can be done when that happens. But that only happens on bound forms, which is to say that if you used an unbound form, that wouldn't happen. But as I noted in a previos response, subforms are almost impossible to do in a continuous unbound form. What that means is that the underlying data on the form has changed, and you shouldn't be seeing that if each user has their own copy of the database that they run.
