With the latest Firefox release, I don't see the background images associated to the Prev/Next navigation links. It turns out that the associated CSS entry is invalid and is thus dropped. Please find attached a patch that fixes the CSS.

This can also be fixed by reversing the 120% and left/right parameters. e.g. - background: url(../images/stock-go-forward.png) 120% right no-repeat; + background: url(../images/stock-go-forward.png) right 120% no-repeat; However, looking at this bug reveals that there was some breakage caused when adding the jquery to the new web site output, to the non-website HTML. I'm going to use this bug to track fixing that as well as the next/previous buttons.
I fixed the standalone navigation style, no other bugs sighted.
I've just reviewed a sample of 8 books of widely different styles and structures without sighting any weirdness attributable to Publican. Happy to call this verified :)
