Navbar links not showing in IE or Chrome?

[indie white]

I have Firefox, and I have tested all my code in firefox; however I have a user who uses chrome and IE on windows 7. He says he can't see the custom navbar links I put up, but he can see the standard ones just fine. The problematic section:
in navbar:

{vb:raw template_hook.navbar_after_faq}
					<li><a href="calendar.php{vb:raw session.sessionurl_q}">{vb:rawphrase calendar}</a></li>
<li><a href="arcade.php{vb:raw session.sessionurl_q}">Arcade</a></li>

                                        <li class="popupmenu">
						<a href="javascript://" class="popupctrl">Chat Box</a>
						<ul class="popupbody popuphover">
							<li><a href="misc.php?do=flashchat&room=1{vb:raw session.sessionurl_q}">Imbeded Chat Box</a></li>
<li><a href="chat/flashchat.php{vb:raw session.sessionurl_q}" onclick="window.open('chat/flashchat.php{vb:raw session.sessionurl_q}','popup','width=750,height=500'); return false">Chat Box Popup</a></li>
						
						</ul>
					</li>
					{vb:raw template_hook.navbar_after_calendar}

I didn't modify any other code relating to this. Do I need to? I think this is probably a simple solution. I don't want all users that use IE or Chrome to have to switch.
