[vB4] How to edit the spacing of popupmenu in navbar

[gorman]

The relevant code, from Firebug is this:

<ul class="popupbody" id="yui-gen3" style="display: none; top: 20px; left: 0px; right: -52px;">

On my board I need the top: value at 26px but I can't find it anywhere (templates, stylevars, css, anywhere).

Many thanks for the help.
