Known issues

This is an issue with the Facebook scripts that RadSocialShare only uses. Facebook are phasing out the support for IE 7 and you can also see the same behavior on their live page (e.g., the Like Button page). More information on the matter is available in the Facebook phasing out support for Internet Explorer 7 blog post.
