That may be a good idea to roll back to service pack 4.0, I'll find out how. The IT guys here at work were shocked whe I told them I was at 5.0. I have other reasons to go with XP, I use Soildwork 2008 at work and I need to run it at home and it doesn't run on W2k.

Thanks for all your help and suggestions, I'll keep you posted.
