What the?!? text in div wraps right everywhere but IE7. IE7 has one word per line?

I've got an unordered list that is sort of a nested javascript helpbox. You click on the help topics, and a scrollable div appears with the help items. Those help items are the unordered list.

Everything is working great in FF, Safari, IE6 (well-I am getting a horizontal scrollbar there in IE6 for some reason) and IE8. But in IE7, it is giving me one word per line and making the scrollbar verrrry loooong in order to compensate. I searched, but haven't seen yet what I'm looking for. Nothing looks obvious to me in the Developer tools in IE, but the issue is replicated there when I switch it to IE7 mode.

Thanks for any help! Joel

Edit: some code...

The helpbox:

<div class="helpbox">
     <h2 class="title2a adjust"><a class="nodecoration" href="javascript:animatedcollapse.toggle('collapse1')">Quick Start</a></h2>
     <div id="collapse1" class="helpbox2">

              <ul id="helpbo">
                  <li class="helpchange"><a href="#">Add Items</a></li>
                  <li class="helpchange"><a href="#">Create Timeline</a></li>
                  <li class="helpchange"><a href="#">Set Reminder</a></li>
                  <li class="helpchange"><a href="#">Detailed Help Topics</a></li>
              </ul>

              </div>
            <div class="closebutton">
                 <a href="javascript:animatedcollapse.toggle('collapse1')">close</a>
            </div>


      </div>
</div>

I'm using jQuery, and the animated.collapse libraries.

js code is:

<script type="text/javascript">
//<![CDATA[
  document.documentElement.className += " js"; // Add js class to the HTML element
  $(function(){
    var $containers = $("#animators > div").hide();

    $('ul#helpbo li a').each(function(i,el){
      var idx = i;
      $(this).click(function(e){
        var $target = $containers.filter(':eq(' + idx + ')');
        // Fade out visible div
        if($containers.filter(':visible').not($target).length){
          $containers.filter(':visible').fadeOut(500, function(){
            $target.not(':visible').fadeIn(500);
          });
        } else {
          $target.not(':visible').fadeIn(500);
        }

        e.preventDefault();
      })
    })
  });


$(".helpchange").click(function() {
  $(".changinghelp").removeClass("changinghelp");
  $(this).addClass("changinghelp");
});

Another stupid noob problem. I didn't have a declared width for those inner lis. It worked fine on the other browsers because it just inherited, but not in IE7
