ImportError: cannot import name '_CursesScreen' from 'asciimatics.screen' (c:\python38\lib\site-packages\asciimatics\screen.py)

_CursesScreen is only UNIX-compatible.
asciimatics also provides the use of _WindowsScreen class can be used instead for Windows-based systems.

Python's native curses doesn't directly support Windows.
We can use this port instead https://pypi.org/project/windows-curses/ for Windows-based systems.

This allows present to run on Windows!

Thanks for reporting this, I'll push a quick fix to remove italics support for now, until it can be done in a cross-platform way in the future.

This should be fixed with present v0.5.1, please reopen it if you still face the issue.
