Close language switcher on iPad

Hey,
We’re using enfold with WPML.
We added the icl_language_selector in the header php.
On iPad we have some issues with the language switcher. One issue is that only the Classic dropdown works. The mobile friendly dropdown doesn’t open at all when we click on it. I’m sure it’s something we did wrong, because if I use the default enfold theme in a new wordpress site, this issue doesn’t occur.
What’s more disturbing is that even if we use the classic dropdown, on some iPad devices the dropdown doesn’t close when we click outside of it.
To be more specific – on iPad2 iOs 6.0.1 it works good, and on iPad2 iOs 6.1.13 it doesn’t close when we click anywhere on the screen.

The changes we’ve made:
in header.php we added <?php do_action('icl_language_selector'); ?> at the beginning of the div with container class under the header_meta div.
In our style.css we defined:
#lang_sel li{width:110px;}

#lang_sel,.lang_sel_list_horizontal {
	float:right;
	padding-top:4px;
	z-index: 200;
}

Any ideas what we do wrong?

Thanks,
Lior
