This may not be the most elegant of solutions but--add this to your page after the map is rendered (map.LoadMap()):
var map = null;
var pinid = 0;
function GetMap() {
map = new VEMap();
map.LoadMap();
$(function(){
$('.MSVE_Map div').each(function(){
$(this).css("z-index", '0');
});
});
}
Our environment:
Firefox 2.0.0.7
jquery 1.2.1
Hope this helps in some way.
