In BS 3.2.0 the checkbox/radio text is not vertically aligned well in some scenarios in IE11 (and Chrome but a little less):

1. Demo: Forms - Basic Example http://getbootstrap.com/css/#forms-example - shifted up
   
2. Demo: Forms - Inline form http://getbootstrap.com/css/#forms-inline: shifted down
   
3. Demo: Forms - Supported Controls - Inline checkboxes and radios - shifted up
   

The screenshots are for IE11
