NextGEN Gallery rendering issues with IE?

I’m calling NextGEN Gallery plugin within a template/theme file using the following call:

<?php
$showslideshow = '[slideshow=1,380,250]';
$showslideshow= apply_filters('the_content', $showslideshow);
echo $showslideshow;
?>

This slideshow works perfectly when combined with NextGEN’s stylesheet in most browsers save for one very important one: Internet Explorer.

In the case of IE, nothing shows at all.

I have the rotating image set left inside a div with text on the right. In IE, neither the image nor the text displays; the entire area collapses. According to Browsershots.com, a couple uncommon browsers have the same rendering issue, but Firefox, Safari, and Opera all render it correctly.

Any idea what I can do to make this work in all browsers?

Is there another technique I should use that would be lightweight and not depend on Flash? In truth, NextGEN is overkill for a simple live image rotator.

Thanks in advance for all your help!
