What the hell is going on with blitz now?

I just lost my last few games of blitz because there's some jacked-up glitch or bug. I move a piece then it unmoves or re-moves and I can't tell who's moving or when the move is happening.

I tried resigning and starting a new game, but it happened again. so I quit and restarted the browser and logged into live chess again. Started a new game and it looks like this (see pic), and meanwhile my clock is ticking!   Can you please look into the bug and credit the games back to me?

Probably not possible to recredit. Also you have such a large amount of games under your belt. Could it be from a faulty java installation? Try removing your history, clearing cache, and a fresh java install. Just a suggestion! Can you play the other modes fine?

Why would it suddenly happen? I play blitz every day, no problem. Just started happening.

Clear your cache and restart your browser.
Using firefox is good.

Do a hard refresh (Ctrl+F5) to clear the page cache if it happens again.

Browser history or Java have nothing to do with it.

Acctually it does.

We don't use Java anywhere on the site with the exception of playing against the computer (and with v3, not even there!). Clearing your cache should help to resolve this issue, though!
