   Are you directly updating the field on the other form? If so, you could   
   get the ping-pong affect and end up w/ a stack overflow. I'd recommend   
   updating the other form's table via a tCursor instead of through the   
   field on the form. ChangeValue only fires when the field is updated via   
   the form - it doesn't fire if the table is updated directly.
