footnote inside table

[Paul Schwartz]

class of document : book - LyX 1.4.1 - windows XP installation  with widows 
installer.
basic language : French.
when I am inserting a footnote inside a table, it is properly displayed in 
the lyx document.
However, in pdf via (pdflatex) the reference of the footnote is displayed 
inside the table, but the corresponding footnote is not. Any clue
Thanks
Paul
