I imagine that it's because the change doesn't come about programmatically - rather it's data driven. One such change might be:

If this.value = x
    thisform.txtMyTextBox.value = "Prog. Changed value"
Endif

in that YOU brought about the change to the textbox. In your case, is it just that you've moved on in a table and the value chages in the text box accordingly? If the value is changed by, say, user keying in a new value then that's InteractiveChange() event.
