Using grizzly on centos 6.4, I have this strange thing with horizon: when I try to view the console of an instance (novncproxy), all I get is

Instance Console

If console is not responding to keyboard input: click the grey status bar below. Click here to show only console

And then nothing. I can "Click here", which gets me a new browser window, with the message

Server disconnected (code: 1006)

and a greyed out Send CtrlAltDel button. Now when I reload this window (typing Ctrl+Shift+r in firefox), I get a functioning console.

When I do this with chrome, I get the console window within horizon, but still "Failed to connect to server (code: 1006)". Then I do the "click here" thingy, a new browser tab opens, and the console is working.

So while I have the basic functionality, I would greatly apreciate to have the console wokring _inside_ horizon _without_ the need to reload. Any hints? Anything I could debug?
