Changing social bookmarks and sub menu = weird hovering

Hi,

I have just changed the positions of the sub menu (should be at the left) and the social bookmarks (should be at the right) with this CSS:

.sub_menu {

left: 0 !important;

}

#top .social_bookmarks {

float: right;

}

So far, so good.

Before this change, when the socials are at the left (as in ENFOLD demo), then when I approach the icon with my mouse from the bottom, then the hover color&link cursor appears as soon as I’m at the bottom of this bar:

After this change, when I approach the social bookmarks with my mouse from the bottom, then the hand cursor/link/hover color appears not until I’m at the top of this header bar – see screenshot:

There must be another file than the CSS, where this “hovering transitions” are set?

Sorry, hope the screenshots help, because I cannot go online with my website right now.

Thanks.
