Yes, OB, intermittently. But I just presume it is the DIS servers, they have seemed snakey for weeks. No Norton firewall, but rather ZA and Netgear router. I do use Norton AV, as well as Panda AV. Ad-aware Plus with Ad watch running background along with Webroot's SS.
I'm running XP with SP2 installed and Norton Firewall and all was well last night, but all red "x"s tonight! Turned off the firewall, but that didn't change anything.
