I often find the poker page displays wrong or out-of-date stuff. For example, it shows me in Under-The-Gun position, but then skips right over me and the bet moves to the next person before I am given a chance to act.

I do a full refresh of the page, and it then shows that I'm actually in the Dealer position for that hand, but by the time it's all reloaded, my hand has timed out.

I just lost a hand with KK in the hole, because this stupid bug caused a time-out while I was waiting for the refresh.
