I'm using it with 2.3.4 BS without any problem - I can't remember doing any mods to make it work. If you have a problem let me know and I'll check for any changes.
The website below was given as an example of one using PS a while back - can someone tell me if the checkboxes to select products to compare is part of PS or a customisation?
