ADE/OPS/Sony Reader, vol 1
There's a difference in behaviour between ADE and the Sony Reader. ADE displays the first file in the <spine> element as the first file in the output. The Sony Reader appears, in the presence of a page map file, to display the first file in the page map.
That's a bit of a problem when the first thing to display should be the cover page. We don't want to see a page number on the cover page. There's a workaround that seems to work for both - put the cover page into the page map file using something like:
<page name=' ' href='cover.html'/>
We are not fans of dodgy workarounds. Oh well.
