[Plugin: NextGEN Gallery] Problems with gallery in posts, big gab between text a

I’ve got a problem. between text and thumbs in a post is huge gab about 1200 px, I can’t find the bug.

look at radiotux

ifixed it with
before:
.ngg-galleryoverview {
overflow: hidden;
margin-top: 10px;
width: 100%;
clear:both;
display:block !important;
}

after:
.ngg-galleryoverview {
overflow: hidden;
margin-top: 10px;
margin-bottom: 10px;
padding-bottom: 10px;
width: 100%;
clear: none;
display:block !important;
}

I don’t know if this is a good way?
