When playing on the BBO Programme. we are receiving popup messages saying they are from BT asking us how satisfied we are and offering us a prize.The message ruins the hand we are playing and we have to turn off and log in again. This is clearly a hoax and hopefully Bridge Base are aware because they need to do something about it. Their website has presumably been hacked and must be unsafe.Friends have also reported instances of this happening. Another message keeps coming up when we are playing asking if we are wanting to leave the site. We delete the message which is often repeated again and again.
