[thelist] Justify with NS 4.x

Hi,
Checking the following url:
http://www.shogix.net/lexique-d-k.html
with NS 4.79, the browser refuses obstinately to justify the text, which
is styled  with CSS p {text-align: justify;}.
But I have three other pages made exactly like this one (same code and
structure, only the  text is different). and NS 4 renders these ones the
way I want, namely with justify text. Compare with:
http://www.shogix.net/lexique-abc.html

When I  reduce the window,  NS 4 now justifies the text!

The test was made on 1024-768 screen and everything is fine with other
browser.

Did I miss anything?
