Well it only took me a mere 4 days to get the job finished which is fairly good by my standards. Unfortunately though the XP upgrade went fine the ADSL modem wouldn't work. Called in favours from various experts but no joy until my son tried his own modem which works fine. No real reason for it and we're putting it down to one of lifes coincidences in that my modem popped it's clogs on the same day I upgraded the OS. Doesn't sound very rational does it but who cares - I'm back on and at what appears to be twice the speed I was working at and with a really great feel to the screen. I love it!
