Just wanted to say well done and thanks for the speed improvements in the latest version. DTPro now opens significantly faster than previous versions, under both Tiger and Leopard. Ditto with the Classify engine firing up on the first use of a session. Thankyou!
Thanks for the nice feedback but I guess the noticed improvements are (more or less) only caused by restarting the application 
I also notice that DTPO opens much faster after running Tool>Backup&Optimize.
