Yes, in a sense... you're running into another quirk of TeX: it doesn't 
attempt to hyphenate the first word of a paragraph. And in your file, 
every word is the first word of a paragraph!

A quick hack to work around this, and demonstrate that it is indeed the 
problem, would be to add something like

   \everypar={\hskip 0pt \relax}

after your \begin{document}. This will allow those paragraph-initial 
words to be hyphenated.
