O.K., I had misunderstood the way preview-latex works. After exiting
emacs I exspected to find some saved state information, now I've read
that it is only within a session. After exiting emacs prv_circ.efmt
and the directory with preview.ps and prev???.png are erased, and I
hadn't examined the filesystem while running emacs.

It would be nice to keep these across sessions (BTW mylatex seems to
work only for documents which have \begin{document} in the master
file, i.e. not \inputed, is that right?). Is that possible?

There are a few problems I still observe in circ.tex:
o "Einf=EF=BF=BDhrung" is (the only) section which show both the preview and
  the LaTeX code underneath it (shifted to the right).

o Under xemacs the baseline of inline math is sometimes higher than that of=
 the
  surrounding text.

o There seems to be a parsing problem in the third item of
  "Einf=EF=BF=BDhrung":
  + The "y" is displayed left to "\item",

  + the text shows "... sich $y$ betragsm=EF=BF=BD=EF=BF=BDig <preview of
    ($\left|\frac...>", i.e. it is displaying the non-preview version of
    $y$ and has swallowed "h=EF=BF=BDchstens um $1$" into the last
    preview. entering the last preview reveals the swallowed text and
    also the preview of $1$ (which is again shifted to the left).

o Similar effects exist further below, e.g. the preview for the inline
  math $x' =3D x+1$ is placed to the left of the paragraph start.

Other that the baseline shift everything can be observed with both
emacsen (emacs-21.2, xemacs-21.4.8). Hm, bug reports for displayed
itmes are difficult, maybe I should make a snapshot and post a URL?

No, not with circ.tex, but with a large document I am working on. The
LaTeX should 8-bit safe, it is from tetex 2.0.2 and I am using it with
inputencoding latin1.

These are the errors:

Parser: Preview snippet 15 out of sequence
Parser: Preview snippet 64 out of sequence
Parser: Preview snippet 69 out of sequence
Parser: Preview snippet 110 out of sequence
Parser: Preview snippet 165 out of sequence
Parser: Preview snippet 528 out of sequence
Parser: Preview snippet 758 out of sequence

There are only a few compared to ~900 snippets (7/900 <=3D 1%). I think
it may have something to do with footnotes, as some are either
footnote symbols or are equations in the vicinity of footnotes.

Thanks!
