non-default currency on cash -> vouchers -> receipts -> new batch is default

[freelock]

This might be an issue with my database, because I did some mucking in the underlying database to fix some exchange rates/get my books to balance.

My currencies are set to USD:CAD:EUR:NGN. In most places, USD is correctly the default. However, on the Cash -> Vouchers -> Receipts individual batch screen, the first currency sorted by alpha is default.

I had an NGN invoice that later got voided -- however, the exchange rate got messed up between receiving the original transaction and the void. I got this all sorted out, but for some reason, NGN still shows up on the batch screen, and is still default, even though when you click "Continue" there are no transactions to receive.

CAD and EUR do not currently appear on this screen.

So I think there are two things necessary -- one enhancement, and one just support request for my books:

Enhancement - change the sort order of the Currency drop-down to match the order the currency is listed in the defaults screen, and make the first one the default.

Support - what might be missing from my otherwise balanced books, that results in NGN being in this list when there are no unreceived invoices in this currency?
