I've come across this before and was wondering if my suggestion\complaint is
on a list for future improvements.

If I accidentally press a key on my keyboard while viewing Contacts in the
Data File view, the keystroke changes the individual contact. I recently
had this happen while on vacation and the one keystroke changed the last
name of a contact and I could not remember the original 'last name'.
Suffice it to say, I was screwed until I could find a backup and reinstall
the latest pst file.

It really would be great if I were offered - 'The contact has been changed,
do you wish to save?'... or something like that. Thoughts?

Thanks, DH
