<p>When you switch between those two views, the translation of the Bible is kept, so if you're in the Quick view and you select the ASV, when you switch to the Advanced view, it preselects the ASV for you. Because of this, it needs to reload the books of the Bible, thus ending up "not retaining the book". To change this behaviour would be a feature enhancement, and as I blogged before, we're not doing any more work on version 1.0.</p>
