Howdy,

The documentation (at the end of ulem.sty) says that the \emph{...} or  
{\em ...\/} command will normally underline and allow lone breaks. You  
can then add the \normalem command so emphasis has normal behavior.  
Maybe I'm interpreting this incorrectly? I see that it doesn't work;  
at least in this case.

Good Luck,
