Sometimes Prince has not space left to put the text of a footnote in the same page of its calling marker.
With inline footnotes all the footnotes of that page get copied on the next one.

An example (suppose the following text gets typeset on page 15):
HTML:

...
<p>... <span class="footnote">first footnote</span> ... </p>
...
<p>... <span class="footnote">second one, a longer one</span> ... </p>
...
<p>... this is the last line of page 15, with a footnote<span class="footnote">third footnote of page 15</span> right here ...</p>

PDF:

this is the last line of page 15, with a footnote(c) right here...
--------------
a. first footnote  --  b. second one, a longer one -- c. third

You would expect this at the bottom of page 16:

--------------
footnote of page 15 -- a. first footnote of page 16

Instead, you get this:

--------------
a. first footnote  --  b. second one, a longer one -- c. third 
footnote of page 15 -- a. first footnote of page 16

It happens when the text of a footnote is split across pages.
I have seen this bug in Prince 9 and in Prince 10 rev. 1.

Thanks for letting us know, we will investigate this issue. Perhaps you could attach a sample HTML document demonstrating the problem, or email me (mikeday@yeslogic.com).

I've edited my previous post, to precise that the bug shows up only when the text of a footnote is split across pages, not when the whole text of a footnote is moved to the next page.

Sorry for my mistake.

I'll try to send you a simple sample file.
