"branch" class overwriting "active" class on links

I've found that the "active" class is being removed when the "branch" class is applied. The solution I've found is to change line 46 of dhtml_menu.js
From this:

$(li).find('a:first').attr("class","branch");

To this:

$(li).find('a:first').addClass("branch");

Just thought I'd post it in case anyone else is having the same issue.
