All o.k. now. Thanks Eric10 & Barmoor. Not sure of reason,left computer on stand by over night and when I resumed it was fine on the web but Outlook Express would no send or receive. When I shut down it warned ccApp was running and saved info,then shut down after saying logging off. It took a long time to shut down. When restarted all was o.k. This is a new box running XP. I was not aware of anything running in the background. Sorry for this rant, might help someone in the future! Thanks!
no problem here, either, and I use Pipex. I did have a problem (month or 2 ago) when I upgraded to AVG 7, but eventually turned out it was caused by firewall conflicting with AVG7 - changed to Sygate and no probs thereafter. But if you've installed anything new recently might be worth uninstalling it temporarily and see if you can send/receive then
