Hi Darren
Can you do a future dated reconciliation, then undo it and check if the calculated balance refreshes.
If that doesn't work go to Reconcile accounts, enter statement date same as opening balance date in the file and check if the calculated closing balance is correct. Also check the calculated closing balance with the statement date entered as 1 day before the opening balance date.
In Bank Transaction screen, filter by the bank account and unallocated transactions for wider date range and check if there are any unallocated transactions before the last reconciled date.
If those steps don't find the issue, send me the serial number in a private message and I'll have a look into it for you.
