another sidebar question

In my site http://www.futuregringo.com I am using the plug “Get Recent Comments” in my sidebar.

Due to the length of the post titles it’s referencing it is pushing my sidebar to the bottom in Firefox and Safari. I’m trying to figure out the code to truncate it within the plug-in to fix it, and keep my line length within my sidebar confines.

I’ve been attempting to use the <br clear=”all”> tag, but it just splits it up more.

Any ideas appreciated – many thanks…
