Definitely, footnotes are the key cause of the problem and they are making the look much worser. If I delete the footnotes it definitely looks better, but I need them... I cannot even put them after text - I need them on the per page basis. You are right that footnote is broken on two pages, but
1) I have the same samples when whole footnote is on one page (do you want me to post it? It looks the same way)
2) I do not understand even why Word does not pot the whole footnote here - it has three more lines and it would fit and fill the gap
3) I definitely see completely no reason for not taking two more lines of text above


By the way: can I somehow prohibit breaking footnotes in Word?
