Xorro Workbook is whiteboarding software for Windows.
Workbook (also labelled AlphaTeach in the UK) is ideal when used with any interactive display or interactive whiteboard, but of course it can also be used without any “touch” interface.
Download or update your version of Workbook (or AlphaTeach) at http://update.xorro.com. You will need your Customer Key to activate the software, otherwise it will download as a 30-day trial.
