The first one has no workaround that I can think of: there's simply no way to do with NW 2 what could be done with NW 1; as shown by the pictures, the paragraph titles had a background color in NW 1, which I implemented in NW 2 with the paragraph shading feature — with the visible result that the shading doesn't honor the floating image area.
The second one is because graphics aren't exactly at the same place, and this can change the layout a lot: this is page 87 when the document is opened with NW 1.4.1, but page 89 when opened with NW 2.0 (0400.0004.02); please notice the second diagram on the page is slightly offset to the right by NW 2.0, and this, in turn, changes the text layout… and it changes it so much that the very same document will need 4 more pages than when printed with NW 1.4.1.
But of course it's no use to print it since the page numbers are wrong…
