the problem is in page-layout/js/widget.js
line :
$('a.widget-action').live('click', function(){
easy patch for the moment is , replace code function by :
$('a.widget-action').live('click', function(){
var css = {}, widget = $(this).closest('div.widget'), inside = widget.children('.widget-inside'), w = parseInt( widget.find('input.widget-width').val(), 10 );
if ( w > 250 && inside.closest('div.widgets-sortables').length ) {
css['width'] = w + 30 + 'px';
if ( inside.closest('div.widget-liquid-right').length )
css['marginLeft'] = 235 - w + 'px';
widget.css(css);
}
wpWidgets.fixLabels(widget);
inside.slideDown('fast');
return false;
});
