I have the exact same problem, but with 802.1x authentication. I've included a part of a screenshot as illustration. Only viable solution is to log out and back in..

After approximitely 5 mins, another one opens on top of the first. This continues, and as the windows take about two minutes to become responsive, they stack up quickly when you are away for a period of time.
