Then there seems to be a slight glitch in that when I view a problem from the library browser, with "Display Mode: None" selected, by clicking the eye icon to open a new window, apparently mathjax is used whatever my personal setting is, and without the options on the problem page it cannot be modified.
Btw, I have a request: Would you please make "Show All Paths" the default in the library browser? I don't see any upside in not showing them.
