When I am using the Spyder IDE the in-built help (usually called using Ctrl-I) does not work correctly in rich text mode:
The plain text version works but when set to use rich text there seems to be a problem with the font.
I am using Python3.6.5 from anaconda3-5.2.0, installed using pyenv.
Is there a connection here with the sphinx library? Do I need to install a font to get it working?
