For an equally unknown reason, it is now working. I did a system restore to earlier today, having tried resetting the hosts file to default (as seen on another thread). I guess I should have let sleeping dogs lie!!
I have had this in reverse. Only today Word would not copy and paste to itself or any other application, but outside of that it did. I rebooted and then we were back to normal. I have had this happen once or three times recently and each time it was in relation to Word 2007. Rebooting cured it each time. - (Not sure I should have said that knowing my luck)
