I tested it only with preview-latex. Suppose we have a LaTeX file: \documentclass[11pt,a4paper,oneside]{article} \usepackage{amsmath} \begin{document} The Euilers formula is: \begin{equation*} e^{ix} = \cos x + i \sin x \end{equation*} \end{document} I can compile and view it in emacs with AUCTeX package by C-cC-c and see that it's correct. But if we try to do a C-cC-pC-p with preview-latex package we get this log: Running `Preview-LaTeX' on `bug' with ``latex -ini -interaction=nonstopmode "&latex" prv_bug.ini "\nonstopmode\nofiles\PassOptionsToPackage{active,tightpage,auctex}{preview}\AtBeginDocument{\ifx\ifPreview\undefined\RequirePackage[displaymath,floats,graphics,textmath,sections,footnotes]{preview}[2004/11/05]\fi}" "\input" bug.tex'' This is pdfTeX, Version 3.1415926-1.40.11 (TeX Live 2010) (INITEX) restricted \write18 enabled. entering extended mode (./prv_bug.ini LaTeX2e <2009/09/24> Babel <v3.8l> and hyphenation patterns for english, dumylang, nohyphenation, bu lgarian, russian, ukrainian, ukenglish, usenglishmax, loaded.
