Text not working in Rhino 5 Windows

Today, I have been opening files only to find that the text is losing characters in my layouts and modelspace. When I set print to vector output, the text appears correctly. However, this is such a headache to work with when I have to select each text object in order to see what it says under the “Properties” Panel.

I can change everything to a different font, which will fix the issue, but when the file is closed and then re-opened, the same problem occurs.

Does anyone know what’s wrong with this?

Hello - can you post a file or send to tech@mcneel.com?
