Footnotes appear in the middle of the page

[Detlev Humann]

Hi! I�ve got the problem that footnotes sometimes appear in the middle of a page. At Herbert�s (very useful) homepage (http://www.educat.hu-berlin.de/~voss/lyx/footnotes.html) I found the hint to use  \usepackage[bottom]{footmisc} to make the footnotes appear at the bottom of  a page. But obviously it doesn�t work in every case. What�s going wrong? I appended a small example file. Thanks in advance for answering! Detlev
