Re: [AUCTeX] how to configure the preamble used in preview

[Chengxi Yang]

Thank you, Ralf!

It is true that the document class "thuthesis" redefines something.
However, in my case I make preview only works for displaymath
environment, and once I switched the document class of main.tex from
thuthesis to article, all previews of equations could be properly
displayed. So I guess simply changing documentclass in preview is
enough for me.
