add_card.py from the example_scripts directory crashes on Windows

[charl...@gmail.com]

When I try running add_card.py in the example scripts directory, I get this error:

/c/local/mnemosyne/mnemosyne/example_scripts % /c/Tools/Python38/python add_card.py 

Log body:

 An unexpected error has occurred.

Please forward the following info to the developers:

Cloned mnemosyne from github master.

I'm on Windows, Python 3.8

Not using a virtual environment, just ensured dependent packages are on my PYTHONPATH.

As far as I can tell, it's because review_widget() is returning a class instead of an instance, in turn because ReviewWidget is not marked IMMEDIATELY=1 and has a comment at the top indicating that this is by design to improve performance.

It works just fine on macOS, though.

Any suggestions on what might be causing the issue on Windows?

The script runs without problems on my Windows machine. Are you sure
you are running the latest version?

Cheers,
