When using the alt key to target it is not uncommon for me to find the smart ping circle appearing and getting in the way of me carrying out my turn. However most of the time I can get it to go away by clicking the x or pinging something. However, during 2 fourlancer games recently once the circle appears it has prevented me from doing anything for the remainder of the turn. I will definately be moving my hotkeys around a bit to prevent this for myself but having it happen because of the defaults really isn't fun.
