Errno 10053 with autocomplete

Hello, I am using Pycharm Community edition 4.0.3 on Windows 7 Pro SP1. I created a virtual environment with Miniconda (Python 2.7.9 and the packages as depicted in the screen capture below).



When I type in the Python console "import networkx as nx" then "nx." and wait for autocomplete, the following error is displayed :

---

Exception happened during processing of request from ('127.0.0.1', 49689)

Traceback (most recent call last):

    self._sock.sendall(view[write_offset:write_offset+buffer_size])
error: [Errno 10053] Une connexion �tablie a �t� abandonn�e par un logiciel de votre ordinateur h�te



Note that the problem does not occur with the Python Shell (and Python 2.7.9 installed to c:/Python27 with the official windows installer from python.org)



Thanks,
