Mark- you've hit the nail on the head! I was about to reply that Vue is fully updated (it's set to autoupdate anyway), but having checked Vue's site I can see it's way out of date (Version 5.01-02 Build 272590). Even when I instruct Vue to check for updates it says it's up to date- how annoying. I'll try downloading the update manually and see if that fixes the problem. Many thanks, Jackson
