The gray box isn't an actual separate element - it is the background color of the <li> which is inherited from the <ul> (in .popupbody). The background for your <a> tag is white (.toplinks ul.nouser li.popup a, .toplinks ul.nouser li.popup a:visited) only it isn't 'large' enough to cover the whole <li> which is why you see the gray. Or, the <li> has some left-over padding/margin and is forcing the gray to show up.
