Featured image interface difficulties

Hello,

This is regarding the “Multiple Featured Images” plugin and how it relates to the image uploader. When l use the plugin, the image uploader/media library window that I get has some bad coding in it, causing the search function in media library to be covered by the list of available images.
I am unsure if this is caused by something in plugin itself or something in the wordpress installation. I am not an experienced coder and don’t know jScript.

Can anyone help me?
