Some themes are missing the Foot asset, and it creates weird behavior sometimes.
Normally you should have an "icon list" on the upper right corner of the comment box, try using that to enter smileys.

$('div.Comment div.Message, div.Preview div.Message').livequery(function() {
Your javascript doesn't add the required span for the css to work.
