disable a97 controls upon reaching "new record"

>I have an A97 form with Allow Edits, Allow Deletions and
Allow Additions properties set. Scrolling through records
will eventually take me to the end of the records and one
more PgDn will take me to a new record. I also have a
cmd button on the form to take me instantly to a new
record.

There are 2 controls on the form I would like disabled
whenever I'm at a new record. I want them enabled at
all other times. Which event property would be most
suitable for this and what conditions do I check for?
