A site I'm working on is using Views and the Views Slideshow plugin to generate a tabbed panel on the site. We modified the output of the plugin to display link names instead of IDs, which worked great. The view set the link back to the node.
We modified the view itself to instead use a link that the user specifies on the node instead of linking back directly to the node itself. Cleared the cache and FF works fine. When I test in IE, it doesn't link anywhere (the anchor's href is actually empty).
I've got all the caching on Drupal turned off, deleted the cache in IE, rebooted... the module itself seems to be outputting different HTML based upon the browser. Any ideas on where to start looking? I'm digging through the module itself right now but I'm not seeing anything that stands out.
