This is odd, as the other info you provide seems to indicate that the
zmq machinery is working fine.  A few things to help debug:

- could you also try with chrome, just to be sure it's not a browser thing?

- hit reload on the notebook page (not just the dashboard) to ensure
there's no cached  javascript around by chance.

- what version of tornado and pyzme are you using?  You can see both with:

In [3]: import tornado, zmq

In [4]: tornado.version
Out[4]: '2.1'

In [5]: zmq.__version__
Out[5]: '2.1.9'
