Query: Disappointing

I was disappointed to learn that this product does not work on Windows XP. As I looked into the matter, I discovered that Sierra is discontinuing the MasterCook line. I have been using it since version 3. It seems like they were so interested in making the interface 'pretty' that they forgot to make it usable. Navigating is a real hassle. It's not surprising that they decided to discontinue the line. It's still very disappointing though.I started using Cook'n and so far, I am extremely pleased. I received an e-mail message from the President himself shortly after registering. I was somewhat skeptical about it but I replied and discovered that the software was developed by a guy who loves what he does. He's been doing it for nine years. I feel much more confident putting my recipes in Cook'n...knowing that at least the product will be supported for years to come.
