Hello Tony

in ui.jqgrid.css there are 4 lines which defines styles inside of .ui-jqgrid .ui-jqgrid-pager and only one line which define the same styles for ui-jqgrid-toppager. The following lines

.ui-jqgrid .ui-jqgrid-pager .ui-pg-div {padding:1px 0;float:left;list-style-image:none;list-style-position:outside;list-style-type:none;position:relative;}
.ui-jqgrid .ui-jqgrid-pager .ui-pg-button { cursor:pointer; }
.ui-jqgrid .ui-jqgrid-pager .ui-pg-div
