@leocg - my translation: It seems the OP now can't look at the eBay site with Opera, though they never had this issue with Opera before (the problem just began "one day"). They've tried various settings (and something involving "use proxy for local servers") but that didn't work. They had a friend look at it and got things going - but 5 minutes later the site would not "let him in again". IE views the site OK. Opera seems to work on Hotmail. They've tried deleting and downloading Opera again, but still have the problem.
@open1949: What Opera version are you using? Are you using Opera's Turbo feature? Are you using a proxy?
