in menu.js I commented this line and now it works....
// aTags[a].onclick = this.a_click;
if (li) {
aTags[a].onfocus = this.a_focus;
aTags[a].onblur = this.a_blur;
// aTags[a].onclick = this.a_click;
// set up onkeypress events as well if orientation is known
if (this.orientation) {
aTags[a].onkeypress = this.a_onkeypress;
aTags[a].onkeyup = this.a_onkeyup;
}
}
