My users requested that I make the icons on the Navigation Toolbar larger (45px instead of 35px).  So, I made the icons larger and set the CSS height rules to 45px.  However, in IE (IE7 & IE8 in compat mode) the icons still appear as if they were sized for 35px.  Is there an IE-only rule that I'm missing?

Sorry about that...  using 4.5.3.

I sort of figured this out.  The problem was the CSS display rules - specifically for display: table-cell, display: table-row, and display: table.  I removed this, which resulted in an unstyled nav bar.  Then I set a static width for the outer div (not a good solution, but oh well) and floated the labels inside of it.

For the icons with text, I set the forum to use only text labels and then used some jQuery magic:

<script type="text/javascript">
jQuery(document).ready(function() {
  jQuery('#NavigationToolbar a.Forum_ToolbarLink').each(function(i) {
     var additionalClass = 'Forum_ib_';
     additionalClass += jQuery(this).text().replace(/ /g,'').toLowerCase();
     jQuery(this).toggleClass(additionalClass);
  });
});
</script>
