Dear John, I just noticed the following new problem with org-mime-htmlize. Here is an example with the following natural deduction in Gentzen style \[ \infer[^{\lnot I}]{\lnot B}{ \infer[^{\lnot E}]{\bot}{ \lnot A & A } } \] the words 48=-plain definitionremarkplain should not appear, but they appear with any equation.png It is maybe the fault of my configuration, but I except in the user.el, I do not see where I can search... If you have some idea. regards, Joseph Vidal-Rosset
