I don't know how to solve this problem---I'm top-posting since the
details below don't matter much---but I can say how to go about solving it.
Since you are comfortable with LaTeX, figure this out at the LaTeX level
first, and ignore LyX. So, e.g,. create a simple file, based on
article.cls, and include a variety of types of equations, e.g., align*
and other things that seem to be causing problems. You may need to try
putting the line that loads extract in different places. Does this work?
If not, the problem lies in extract's treatment of those environments.
If it does work, try shifting the document class to classic-thesis. Does
that work? If not, then there's some incompatibility between
classic-thesis and extract. Those are both LaTeX issues. I'd try writing
the extract maintainer, or asking on comp.text.tex or somewhere like that.
If all is well on the LaTeX side, try importing your simple LaTeX file
into LyX. Alternatively, just try creating the same kind of file in LyX.
If it no longer works, then export it back to LaTeX and compare the two
files. They will be different. It may be that the line that's loading
extract is coming at a different place.
