Windows 7: Server error when starting Spyder Notebook

[Max Bberg]

Hi all

I'm a newbie (so please go easy :). 

Environment: Windows 7, Conda 4.4.9, Python 3.6.2, and Spyder 3.2.6. I regularly use Jupyter notebook outside of Anaconda.

Today, I installed spyder notebook but when I run it, it starts a Windows process called "Server Error" and Spyder won't open. However, if I kill this process, Spyder immediately opens and Spyder Notebook seems to work fine (sometimes Spyder struggles to find a kernel for the notebook for some reason but it's mostly OK).

Is there any way to prevent this Server Error process please? And is it perhaps connected to the kernel struggles?

Many thanks for a great app

Max
