Price and orders update? As in on the page itself? We have that... are you using Firefox?
I am using Firefox 27, but i checked Chrome - same behaviour: no new buy/sell orders, no new history records.
If I reload the page, the information is updated.
Bittrex updates without problems, Mintpal sometimes freezes.
Crypsty and Poloniex without problems too, but I almost do not use them.
