Could not open the revision3 file, so I got a copy from the magazine site (23-March-2013 9:42)
While paging through the file I still get thrown back to page 3.
If I open the table of contents I see 3 times an
unnamed item. I see a
here item. There is also twice a navigation point 20.
Some links work. Many just jump to page2 though the noc files points to the correct id. See below.

I could not fix this. So I opened the file in Sigil and put a split marker before each item starting with 'editorial. That only takes a few minuted and then I had Sigil apply the split. That action generates a html file for each item. The original file is kept as first page with the list of items. I also generated a new toc.ncx file in Sigil only using <h3> tags as items and then started browsing the (now 85 in stead of 62 pages) file on the EntourageEdge. At page 82 ....... my battery was empty (it was already low when I started this evening)

.
So I hooked it on to the power cable and gave it another shot.
Each item starts on a fresh page. I noticed a blank page at the end of some items but paging went ok without being thrown back at page 2 or 3. The toc items also worked. I seems that my device likes this setup of each item as a chapter best.
Here is a public link to the file amended via Sigil.
