Many programs wait to log an account number for that list until you actually take an action on that account. Since the purpose of that feature is to allow you to work with the same account again, the idea is not to clutter it up with numbers that were entered by mistake, fat-finger errors, etc. This feature is a very handy tool but it’s not intended to be a reliable audit log of every account number you ever accessed for any reason. (See the related items below for tips on using the SECAUD security audit file for that purpose.)
