Small mobile issues

Hi,
before we are going finally to launch our site – and I’ll hopefully don’t bother anyone again after that – we stumbled about two smaller problems while viewing the site on smaller mobile devices (at least iPad vertical).

1.) Our main Logo doesn’t show up on the main page (all others are working).

2.) The menu (which we display on all pages, except the homepage) ist getting to long and the last item is wrapped and then will be shown on the main image, Is there are way to keep it within in the div?

At first I thought this might be because we change the look og the menu with this snippet:

/* adapted menu settings */
.main_menu ul:first-child > li a .avia-menu-text {
	top: 20px;
	position: relative;
}

But even if I comment this out the behavior will be the same.

Thanks in adavnce for your assistance.

Michael
