Incorrect currencies with payments

I've sent out an invoice in USD. My default currency is EUR. I recorded a payment, but then deleted that payment.

Now, I want to add a payment again. When I touch the 'account' dropdown, the displayed payment currency changes from USD to Euro, which is not desirable.

When I do record the payment without touching the 'account' dropdown, and the payment is recorded for the wrong account, the payment *is* recorded correctly, but the actual payment is not reflected in any of my balances.

Both appear bugs to me.
