We are proud to announce the release of Resolver One, version 1.7. Resolver One is a Windows-based spreadsheet that integrates Python deeply into its recalculation loop, making the models you build more reliable and more maintainable. For version 1.7, we've made the code that you add to buttons on your worksheets execute in the background. This means that you can interrupt them easily if they run for too long, and also stops the rest of the application from pausing -- so you can keep working on other spreadsheets. You can read more about Resolver One here: <http://www.resolversystems.com/products/resolver-one/> We have a 31-day free trial version, so if you would like to take a look, you can download it from our website: <http://www.resolversystems.com/download/> If you want to use Resolver One in an Open Source project, we offer free licenses for that: <http://www.resolversystems.com/opensource/> Best regards, Giles -- Giles Thomas giles.thomas@resolversystems.com +44 (0) 20 7253 6372 17a Clerkenwell Road, London EC1M 5RD, UK VAT No.: GB 893 5643 79 Registered in England and Wales as company number 5467329.
