Come on... three stars off for a simple calculation issue. Jeeze. This is a stable, well thought out, OSX app that has an author who is committed and in it for the long haul. Best of all, it works. I hardly ever loose an auction, and I bid a lot. Futher, $30 to keep an author engaged is chicken feed. How many shareware apps have disappeared because of lack of support by users. I'll bet you guys who are complaining never pay your shareware fees and never work with the authors to help them improve their apps. Oh yeah... bone up on your second grade math skills.
