bank account balance not reflecting actual balance

Thank you Steven

That is exactly the answer.

It is actually a feature I can use to make sure I have sufficient funds in the account for the upcomming tax payments now that I know what it shows :-) 

There is a figure displayed in the business insights and the bank reconcilliation screen for the balance of a bank account. It is completely different to the actual balance and does not reflect any previous balances. Pressing the blue arrow beside the balance displays a screen with the correct balance. i have no idea where this balance comes from but it is very missleading. I tried reconciling the bank account up to date - it did not change this figure. I dont use live feeds, I prefer to manually load my bank information. Anyone have any ideas?

could you elaborate on where you're seeing the account balance?

for example are you running a report? if so, which report and for what date range?

Where do I see the incorrect balance? - Many places, here are a couple of examples:

In the accounts list - the 'bank account' account shows the wrong figure.

In the 'Bank Register' screen the balance in the top left corner also shows the wrong figure.

If I click the balance button beside this figure it shows the history of the correct balance and the ending balance on this screen is correct.

What might have caused the problem? I use mutiple currency bank accounts. I recently paid a Yen invoice from this account. Realising my mistake I entered the payment journal and changed the account to the Yen account. I suspect that there is an object file somewhere that generates this balance which did not pick up the reversal of the payment.

Any thoughts on my problem?

While I suspect I may know why it happened (but I might be completely wrong) I have no idea how to fix it.
