Messes up my toolbar

I love how easy this plugin is to use, but when I use it on one of my sites that’s using the Vantage theme by AppThemes.com, they dont seem to mingle well. If the user is logged out, the toolbar is normally hidden, but when this plugin is active, it puts a big white space where the toolbar would normally show if logged in, and then below that it shows the toolbard which is supposed to be hidden at the point.

Any idea how I might be able to resolve this?
