Thanks very much,
Midnight - I do just link off the Network, but as bigstar correctly pointed out I chose the settings per user - which of course is not an issue, because only I can run it, because it's on my personal network drive.
Cheers
Ed
P.s. because I don't have access to regedit, I just re-installed on the local drive, un set individual settings, then uninstalled it, and now all works just hunky dory
