title: Do access subforms that are not visible still update/requery? If not, can this be behavior be configured?
body: <p>I have an old Access database that is being upgraded to work with Access 2007.  The client is complaining that it is slow now.  I am looking for ways to optimize it.</p>
  
  <p>There is one subform that is in a particular tab on the form.  I have been wondering -- does the subform still update/query even when it is not visible?</p>
  
  <p>If this is configurable --- how?</p>
