In the last release, the way the cash book is updated was changed so that as new records were added or changed, it did not reload the entire list from the database again.  This made the screen update faster.  However the side effect the was the account balance shown on the screen was not being updated.  Previously the balance was recalculated after a complete reload. As of version 9.3 the balance is again updated dynamically, without needing to do a complete reload.
