I've noticed that the content of the bibliography table differs after printing.
I mean the structure of the table and the number of sources in the table on a given page.
Please take a look at my screenshots.
The first screenshot shows the end of the first bibliography page. The last source on this page is No 10.
The second screenie shows the same document just before printing (print preview) - the source No 11 was moved from page 72 to page 71.
I'm not sure if this has something to do with the bibliography module or maybe with Word's tables?
