Well, hiho322, unfortunately I still don't have an answer for you. We will just have to give it a try when it is released. The problem you and others have been having is due to bugs within the Mac hardware when it comes to 64 bit processing, and we do not have one of the couple affected machines to test on, so it is difficult for us to predict how the Mac will handle the code. The Lion version uses a different set of tools than the Snow Leopard version, so I am optimistic, though not positive, that it will work.
