Question : Access 2003 has no On Change event for Controls

I have used the event “On Change” currently in a 2007 database to save the record automatically each time the field is changed per the client’s request.  Worked really well.  I now have a similar situation with a client running 2003, but I see no “On Change” event.  Ideas for a similar work around that won’t bog down the system as they move from field to field?

Answer : Access 2003 has no On Change event for Controls

I am using Access 2003 and it does indeed have an "On Change" event. ??????
