Yes, I see it.
I am currently connected via wireless to a mid speed server. Right now I am at the liabray, but I recieved the same could not connect message at work. There IS a proxy in both place. I am using Win XP home SP2, IE6. I have zone alarm as my firewall and am willing to turn it off. I DID turn it off at work for a few attempts, but today it was on.
