I think i found,
Can you try to replace function showPage in main.js by this one :

function showPage(pageURL,button_id) {

hideContent(pageURL);
if (selected_button!="" && button_id!=selected_button) {
sendToASUnselectButton('anim_'+selected_button);
}
if (button_id!=undefined) {
selected_button = button_id;
}
}
