In various situations, but mainly when you add an internal transfer manually, HomeBank searches for transactions that match the criteria (see below) for the target part of the transaction and this dialog will always popup to select the action you want to, including create the target transaction.
In version prior to 5.8, this dialog was only showed when at least one operation was found, otherwise the target part of the transfer was created automatically without any confirmation.
    You can change or return to this previous behavior by disabling the option in Transfer behavior section of the preferences.
