Last spring, when such mis-displays were frequent in my "course" with practice versions of my Differentiation gateway, I punted and changed default display to be Images. That is not something I want to do again.
An individual can change their configuration for MathJax (right-click or ctrl-click on a MJ element displays a popup menu). E.g., I have
Zoom Trigger = hover
Zoom Factor = 200%
(and will demonstrate that to my classes next Tuesday), but I have not chosen
Scale All Math to be larger than surrounding text.
1) it appears MathJax configuration by an individual would need to be done for each browser on each client computer.
2) Stix fonts are installed on my client computer (see "local STIX" in Danny's screenshot).
I've seen vague references to an installation of WW+MJ being configurable to avoid the mis-displays we've seen. If that is feasible (& reasonable), where should we look to find directions for doing that?
