It just keeps "witing for first trade" here. What's going on?
Open up the console, FF or Chrome, right click on page -> inspect element then select the console tab in the bottom window pane that comes up.
If you see errors, paste them.
If you see nothing, nothing is moving. Right now I am seeing periods of 30+ seconds without trades, so if you closed the window that fast (which is a long time watching a circle spin round) you would have experienced that.
