jojo69: Sometimes, the sign in page won't even show - says it has found site, but waiting reply??
Then when I do get to sign in page and I write my user and pass word - Again it is ages in trying to retrieve the page!!
Could be a couple of things, first is your firewall may have decided to block it, that can happen especially if its NORTON, or the actual program may have got damaged, corrupted files etc, in which case you need to reload a fresh copy.
Turn off your pc, restart when all up and running try switching off the firewall and then try accessing yahoo, if it works switch on the firewall, if not, switch on the firewall

you need to protect yourself, a few mins without the firewall is ok but not for too long.
iif the above has not fixed it try plan b reinstall
