In 1.3.5, again from my bookkeeper:
"And as long as they are fixing things, when I am done with an invoice and
want to start another, I choose the "New" button and get a blank invoice.
However, when I fill in the vendor and hit "Update" the screen goes blank.
The only way to start a new invoice is to go to the "Add Transaction"
link on the right. Not a big deal, but a bug nonetheless."
