many thanks for the fine piece of software that is lichess and the hours of entertainment it provided me in the past.
Unfortunately, ever since you migrated it to winsockets, it simply won't work for me on my windows 7 x64 machine OS any more. I am able to create a new game, but unable to move my pieces - the page simply refreshes and moves my piece back (a "reconnecting" message sometimes flashes briefly). This occurs on Firefox, SeaMonkey and Chrome when ran under windows. Under linux, everything runs smoothly. I am attaching screenshots and the full log from fiddler during a recent (attempted) session that show a pattern of repeating websocket handshakes, perhaps it will help you identify the issue.
Please look into it if you have some time, this issue makes the site unusable for me (i can't afford to shut windows down and boot linux every time i want play a game of chess :-( )
