frameset problem

[anjutosi]

I'm a newbie, I know HTML and CSS well but always have this problem.
I have a 2 frames pages, want to have the menu in the left frame and link contents in the right one.
My menu is working fine except the target. Even if I have
<item label="Ship Models" url="ships.html" target="rightFrame"/>
or
<item label="Ship Models" url="ships.html"/>
the page opens always in a new window, as if I had taget="_blank".

My click handler function is
menu_mc.onItemClick= function(node:XMLNode, level:Number){
getURL(node.attributes.url, node.attributes.target);
}

Can anybody help me?

Loading in Mozilla, it's working fine
