Jumpy L2 Nav when using single list item

[rcrisler1]

We've noticed a behavior on some browsers when level 2 navigation consisting of single list items is used.

The single list items display one or two pixels higher than lists with multiple items, resulting in a visible 'jumpiness' in the way the level 2 nav line displays as you mouse over the level 1 nav line.

The fix is to add another list item to the single list item.

Before

Code: Select all

        <li class="first"><a href="http://www.adobe.com/acrobat/readstep.html">Download Acrobat Reader</a></li>

After

Code: Select all

        <li class="first"><a href="http://www.adobe.com/acrobat/readstep.html">Download Acrobat Reader</a></li>
        <li class="first">&nbsp;</li>

And yes, the nonbreaking space matters. Only God and Berners-Lee know why.
