No kidding on the readable dials! And the new library structure, and no crosstalk. To me, that was enough to warrent the upgrade price. My problems have gotten a lot better since SR2B5 too. Still not quite there yet, but a great improvement. I think that by removing the security code things will improve a lot. I know the footprint of the program should shrink, and it should load faster. I'm hoping the calculation speed will improve too.
