Font Distorted

[LVanarsdall]

Hello. I am working with a teacher whose problem is that when he opens the app, the font is distorted in size and cannot be read. He is using WIndows 10.I have had him chnge the resolution on his computer and re-install the software, but he still has the problem. Does anyone know any next steps? Thanks.

Have you tried <ctrl>+ and <ctrl>- ?

Thank you. That does make a difference.
