moves won't register in online chess

I've been having this problem for few days now, where the moves won't register. I have to hold the piece on that square for at least 5 seconds before releasing, for it to register the move

EDIT: I got a new mouse and the problem is fixed

thatsmy problem to.I CANT play all legal moves.thatsplaying on my new tablet. The pc works fine. why is the tablet diverent?

Are you using the Chrome browser?  In Chrome I have to drop the piece on the top edge of the destination square for the move to be accepted.

sorry for not updating the post. I realized the problem is my mouse, so I'm getting a new one

That's good to know, but a similar bug still exists (at least in Chrome), namely, if I submit a move after the page of the game was open for too long (>30 minutes, I guess), the move isn't made and I have to submit it once more (the second attempt is always successful). I guess the server architecture is necessarily such that it can wait for a response for a limited time and then the page needs a reload, but the timeout threshold can be increased to such a value that it's invisible to most players (like to several hours).

Same issue here, moves just wont register. Although I can see the shaede squares, the pieces dont move.

Edit - I'm also using Chrome. And to be precise, opponents moves dont register. So I have to move its piece to the designated spot in order to be able to move my piece. Quite weird...

Do I take it right that the site is developed primarily with Firefox in mind and so it's the recommended browser for bug avoidance?

I'm using firefox
