The Visual Style Builder is not updated with the latest Q3, 2012. I could not give you firm estimated, but it is in our to do list, but we need to provide a few more fixes in the CSS files to ensure we will not release some major problems.
For now, you could take the latest control`s CSS released form the skin folder and to compare with the version Visual Style Builder outputs and manually add the necessary changes. Note that if the problem is with the layout, it will be necessary to check the base stylesheet also.
