Nope not to my knowledge and I belive that the other users on the pc couldn't have changed it since I personally cannot have changed the refresh rate. I can run in safe mode to try and fix the problem but I am havinga hard time viding hwo to cahneg it
Also to be double sure use a packet sniifer or somethign liek wpe pro and put fals information in and see if it goes to anywhere else but neopets. they cannot hide the post data from a packet sniffer unless they are good, but then you'll have to watch them take your account
