I am working in with current version of Jupyter notebook. And I encountered a weird problem - the command palette won't open, even if I click on the icon just below the menu bar.

Server Information:

You are using Jupyter notebook.

The version of the notebook server is: 5.2.1
The server is running on this version of Python:
Python 3.5.4 |Anaconda custom (64-bit)| (default, Oct 27 2017, 11:35:13) [MSC v.1900 64 bit (AMD64)]

Current Kernel Information:

Python 3.5.4 |Anaconda custom (64-bit)| (default, Oct 27 2017, 11:35:13) [MSC v.1900 64 bit (AMD64)]
Type 'copyright', 'credits' or 'license' for more information
IPython 6.1.0 -- An enhanced Interactive Python. Type '?' for help.

The chrome console gave below error message:

it seems new commandpalette.CommandPalette(this) called Jed.gettext which throw the error.

I've re-installed jupyter, but the problem persists.

Appreciate any help!
