hi, when i sign into ebay and try to view the items i have for sale i have to confirm my identity by talking to someone through their live chat.It says that they do not recognise the pc im using even though i only have one. this has never happened before and i have had to do it 3 times this week. ebay say it is because im clearing my unique identifier which tells them who i am and what my pc is. i know it has something to do with me clearing flash cookies. i have tried by not deleting any cookies, that made no difference. i have vista and adobe flash installed, any help would be great, with thanks.
