CSS problem

When I show a text before / after a gallery , the "float: left" cause a problem, that the

<div class="ngg-galleryoverview">

container , didn't work as block element, strange...

no images were found

Update : With width: 100%; it worked now under IE7, but not under FF...

Update 2 : Now when I use clear:both for the navigations its also ok, but is this the solution ?
