Fixing this Python 3.6.1 issue will probably require modification to the Python curse stdlib. Here is the ncurses 6.0 author’s description of the notable changes that he made
to ncurses 5.x in order to produce ncurses 6.0 (excerpted from: http://invisible-island.net/ncurses/announce.html):
Extend the cchar_t structure to allow more than 16 colors to be encoded.
Modify the encoding of mouse state to make room for a 5th mouse button. That allows one to use ncurses with a wheel mouse with xterm or similar X terminal emulators.
