I have a MacBook Pro with Snow Leopard. I partitioned the HD, installed Lion on the new partition and used Migration Assistant to copy settings and Applications.
I now have duplicates for most Applications, many seem to point to the Snow Leopard Applications.
I can't find a way to easily identify which apps are Snow Leopard so I can delete them.
The alternative would be to trash the Launchpad db, but how do I prevent Lion from recreating the Snow Leopard items?
