Cannot edit/create materials

Am I missing some important configuration or there’s a bug with the panel for creating/editing materials?

I downloaded and re-installed Rhino a few hours ago because the old version started crashing at start.

and now it started crashing again… :thinking:

This whole thing started after installing a new font in windows.

And now it’s fine…

Is it possible that Rhino doesn’t like TeamViewer?
I stopped TeamViewer session and Rhino is working well again.

Maybe…though it seems like it works for some people.
