I am currently experiencing a problem with the console under Chrome -- it says it's establishing a connection, and then I can put in one or two characters before the console freezes. No more characters until it repeats the "establishing a connection" message, and then a few more characters, maybe, or not.
In general the console is for me unusable under Chrome within our network.
So I tried using IE. In this case, I get a message about was sure about displaying content, then a screen freeze for about 30 seconds. Then the "establishing a connection" message came up for the second time. Then I got a prompt. I typed "ls", got a list of a few files, and now the screen is frozen again.
30 seconds later or so, another connection message, another few characters, screen again frozen. 30 seconds later, connection message, another hundred or so characters.
If this is some new firewall interaction, it would be nice to understand it better, but it doesn't make sense that it would allow a hundred or so characters to pass every once in a while.
