When I log on to ebay some of the ads on the welcome page are missing and a 403 error is shown. Also when I log on to my ebay account and put something in to my watch list I am logged out and put into a guest account. This only happens when ZoneAlarm is running. It happens with both IE6 and Firefox. I've turned off all of the Privacy stuff in ZoneAlarm but the problem persists.Any ideas as to how to fix this?

Operating System:Windows XP Pro
Software Version:6.0
Product Name:ZoneAlarm (Free)
