No what I am saying is this is not an issue with reviewpost but a problem with your hack not our code.
The CSS is not different at all between 3.32 and 4.02 and unless there are changes you made to the styles I would not think this is your issue.
My suggestion is to look at your hack. View the source of your page. View the template directly by url make sure your changes are there. review your code to see if anything your doing might be an issue
Nothing has change in our code from 3.32 to 4.02 template wise that would prevent you from adding some html somewhere as long as you add it correctly.
