Here are some bugs in LaTeX supporting programs that affect functionality of LyX.
Some of these bugs may be squashed in more recent distributions.
LaTeX bugs
- Bug in Babel "Extra \else". There is a bug in the babel package that affects formatting in large documents in an erratic way, indicating a spurious
"Extra \else" error that stops LyX and prevents viewing. To avoid it, do the following: In babel.def replace the three occurrences of \noexpand\bbl@restore@actives with \protect\bbl@restore@actives. (See the thread babel + fancyhdr + natbib = ! Extra \else in the comp.text.tex group.)
- Bug in Babel/graphicx "figures in turkish and latin documents". There is a bug in the babel/graphicx packages that occurs in turkish and latin documents. The
\includegraphics command does not work in these documents, and you will get a LaTeX error if you use figures in LyX with turkish and latin documents. See http://bugzilla.lyx.org/show_bug.cgi?id=2005 for details and a workaround.
- Bug in dvipng "instant preview". A bug in dvipng version 1.6 causes font problems in instant preview (an option in Preferences -> Graphics). If math inserts vanish partially or totally, or characters in math inserts disappear or are displayed with incorrect glyphs, try the following: Remove
dvipng.exe from the ...\texmf\miktex\bin\ directory (or its equivalent in other systems) and reconfigure LyX. This bug allegedly will be cured in dvipng version 1.7.
