There're actually half a dozen or so themes to choose from if you follow the Profile link under the header image. I don't recall how much they vary from one to the next, but it's possible that one of those might work better for you.
I'm not sure if the issue has to do with my work computer or with the ComNet itself, but at the moment I can't get the theme to update for me when I try. If someone else can try it and see if it works for you?
