MIKE  Very slow on PowerBook G4 running 10.5.8. Apparently won’t import all data from previous version. Very disappointed. Paid for upgrade almost 2 1/2 years ago, and then get an unworkable product, not satisfactory. I did call and have received a promise to refund my money. Assuming that happens, it does resolve the issue. I have for many years used and will continue using the 5.3.2 version since it functions OK. Guess I’ll need to find something else for the future.
