not that i know of, but you might try an unconventional layout to simulate
it. instead of a single continuous form, create two subforms in an unbound
main form. set the first subform's DataEntry property to Yes, to enter new
records only, and make the subform just "tall" enough to show one record.
set the second subform directly below the first subform, and set its'
AllowAdditions property to No.
so you can edit existing records in the second subform, but not add new
records; and add new records in the first subform, but not edit existing
records. to force newly added records to show up in the second subform, try
requerying the second subform in the first subform's Current event. i've
never used this setup, but in might work for you.
