Resolved: I cant move a piece.

My piece is sticking to the cursor when i click it. I cant drop the piece to the board. This is not happening before. and my connection is fine. I'm using google chrome, help please. how can i fix it.

wabby, will you try a hard refresh on the page that is giving you trouble, please? This is done by pressing CTRL + F5 (PC) or Command-R (Mac) on that page. Often, this will resolve the issue. 

With Google Chrome, we've found that a couple extensions have been interferring with live chess functionality. You might try disabling them one at a time to see if any are affecting your game play.

Thanks.. I disable the extension(utorrentbar) and it works.. 

Great, good to hear. :)
