Thanks to Steve who used jing I have resolved this issue. It all came down to the setting not being where I expected it to be. I’d have expected all the settings to be available via the vista control panel. In this case the enable auto-rotate is only available through the ThinkPad Tablet Shortcut menu then clicking on the Settings button (which appears to be greyed out but is active!). So thanks Steve and hopefully someone else will find this useful.
