<div> <h3>Blah Blah</h3> <form class="form-horizontal" role="form" name="xxxForm" novalidate> <div class="container"> <div class="row"> <div class="col-xs-8"> </div> <div class="col-xs-4"> </div> </div> </div> </form> </div>Previously this worked as expected. Now the 'col-xs-4' div appears outside the modal boundaries - in fact the area taken up appears to be related to the underlying page width rather than the modal width. Can't find anything related via googling. Anyone else experienced this ?
