Setting up my WordPress blog, minor annoyance!

[Carbonic]

Im in the process of getting my blog started, and I just have a really minor annoyance that I can't seem to figure out how to get rid off, here is an image that will make it easier for me to explain:

Basically, I want to remove all of those lines that appear under each of my links, I want to keep the line under where it says "Blogroll" but after every link I think is really unnecessary.. Can anyone help me out with this?

oh, and heres the link to my site: http://iamjaybot.net

Hi

.widgetblock li {

padding:5px 0 8px 0;

background:url(images/sidebreak.png) bottom left no-repeat;

}

Switching to background:transparent; or just deleting background altogether should do the trick I think (only looked briefly though).
