Portfolio in Articles Covers Text (Internet Explorer)

I'm part of the beta testing group and recently my portfolio was set so it showed while reading in articles. While this is a fine feature, when I open an article and scroll down to where the portfolio starts, the scroll bar for the portfolio covers about the first half to 1 inch of each line of the text the rest of the way down the page. I can generally get the gist, but it is annoying when I am trying to read an article. If that could be fixed, I would really appreciate it. Thanks.
