I have modified the code slightly for Blogger CommentLuv on JSKIT echo system.
[bug fix] .. Some users seeing “recent undefined” being appended to their comment. Fixed
[improvement] .. The info panel was sometimes obscured by a sidebar whose Z-index was higher than the comments column. Added code to append the panel to the document body and then move it to the position of the mouse overlaying any other elements.
All blogger blogs currently using CommentLuv have already been updated, no need to download or install the plugin again.
