the only (unverified) way I know of to address this is to enable
BDE Callbacks and write appropriate functions in your app to handle them.
BDE will notify you when other sessions make database changes and
you can refresh in response.
See BDE32.HLP "callback"
kind of a hassle. maybe it's time to consider a different dbms
