Gmail’s Paging Buttons

I like Gmail, especially the interface. I feel like every time I use it I discover a slick new aspect to the interface. One thing I don’t like is the paging buttons, to move back and forth between older and newer messages. Almost every time I need to move back a screen I end up scrolling the ad that is right above my messages. I think that a little more separation would be good, or somehow calling more attention to the paging buttons, rather than the ad scroller.
