Recent Comments WP 1.5 and Smilies

Using the Recent Comments Plugin by MtDewVirus and having issues with when users use smilies in the first few words, it seems to overlap on the words in the Recent Comments section.

Here is the plugin that I used:

How can this be resolved?

Appreciate the help.

Thank you.
