Interesting, but it splits the screen?

Maybe its because I havent updated to mavericks, maybe its because Im on a 24-inch which apple doesnt make anymore, but at the top of my screen where the bar is that has the Apple Icon, Finder, etc. for some reason it splits it in half. The side with the Apple Icon is grey, while the side wih the time, language, wifi connection, etc. is white. Not sure why this is but its kind of annoying. Otherwise a good app.
