The entire menu bar is all javascript.  Here's the "Tell a Friend" entry
(simplified):
< td id="cmsMenuBar_x..." class="cmsMenu_up cmsMenu_up_cmsMenuBar_xehd..."
onMouseOver="cmsMenuObject.highlightSub( 'cmsMenuBar_xeh...', '2')"
onMouseOut="cmsMenuObject.clearMenu( 'cmsMenuBar_xehd...', null, 0.5)"
style="cursor: pointer" onClick="cmsMenuObject.clickGo(
'/action/tell/?_adctlid=v%7Cxef...', '_top'); return false;" nowrap>Tell a
Friend</td></tr>

There is no href there, only an onClick. That makes it a Form and httrack
doesn't click on forms.
