For some reason, the dropdown menus on my version of Mathematica 18.104.22.168 sometimes become black in the middle of a session so that I can no longer see any of the text. I am using a MacBook Pro from 2015. An screenshot of the problem is included at the bottom.
Does anyone know why this is happening? There's no way for me to cause the menu to go back to being the normal colour without restarting the program.
