Sidebar Widgets Issue in Chrome and IE

Hello, I recently added the sidebar widget “Executable PHP Widget” so that i could write PHP code into a sidebar widget. This was because I did not like the default sidebar widget look/feel of my current theme (45 Degrees 1.0 by Igor Penjivrag).

It looks beautiful in Apple Safari and Firefox, but in Google Chrome and IE6 it appears broken and missing many of the widgets. Does anyone know what is needed to resolve this issue? It is quite frustrating, as many of my readers likely use IE. Thank you.

Below is what the sidebar.php code reads, if that helps.

<div id="sidebar">

<ul>
<?php 	/* Widgetized sidebar, if you have the plugin installed. */
		if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?>
<?php endif; ?>
</ul>
</div>
