On the cashbook screen, after you press the Load button, the current calculated bank account balance is now shown in the lower left corner.
The bank account balance is calculated based on the opening account balance and date set on the bank account setup screen, plus the value of all transactions in that bank account since that date.
After the load button is pressed, as new transactions are added or deleted from the system, the account balance will be automatically recalculated. However if transactions are also being entered by another person on another computer, these transactions will not be reflected in the balance until after the Load button is pressed again.
