Tabs overflow under right sidebar in Drigg module admin (css issue)

Not sure if this will help anyone but in my case the tabs were overflowing and couldn't access some of them (Related Links, RSS Import), after realizing that this was fixed in the included 4Plus theme, I sniffed around and added, with small changes, these lines into my theme based on the drigg_theme to override or alter presentation to work.

/* Fix tabs in admin menu */
#content_center .tabs {
width: 100%;
margin-bottom: 5px;
padding-bottom: 0;
}

#content_center .tabs::after { /*clearfix*/
height: 0;
visibility: hidden;
content: ".";
display: block;
clear: both;
}

#content_center .tabs li {
float: left;
margin-bottom: 5px;
}

#content_center .primary a {
padding: 5px;
margin-left: 0;
margin-right: 3px;
line-height: 1;
position: relative;
}
