CFP at startup


A few weeks ago CFP window started to appear at start up occasionally, and since recent update to 3.8.64739.471 it’s appearing 90% of the time. Doesn’t seem to correlate with any warnings/action required. I just watch the initiating message and a blank active connections box, then quit. Firewall seems to be running normally otherwise, not had any issues. Any suggestions as to cause of this behaviour?
