[texhax] Precision on: bug on vertical spacing w/ hyperref+seminar

[Laurent MUGNIER]

Hello all,

Here is an additional piece of information about:

>With seminar (and slidesec.sty) the vertical spacing between a slide heading and 
>the text changes depending on whether hyperref is loaded or not.
>
>This bug occurs at least when the following combination is true:
>- the text begins with an itemize environment,
>- the slide heading is centered (default with \slideheading{} as defined in 
>slidesec.sty).
>
>It seems that with hyperref, there is a blank line before the first item of the 
>itemize environment that constitutes the text.
>
>This occurs with v6.73n that comes w/ our 2.0 teTeX distribution as well as with 
>the latest v6.74m downloaded today.
>

The unwanted additional empty line is triggered by the command \hyper@@anchor on line 
4055 of hyperref.sty v6.74m. This line is part of the definition of \slide at heading 
and is the key to the hypertext navigation in the slides )-;. If this line is 
commented out then the empty line vanishes.

Any help will be most welcome...
Thanks in advance,


        Laurent Mugnier.

PS: I attach a mini-minimal example.

\documentclass[a4]{seminar}

\input{seminar.bug}
\autoslidemarginstrue
\input{seminar.bg2}% cf. http://www.tug.org/applications/Seminar/

\renewcommand{\printlandscape}{\special{landscape}}% useful WITHOUT hyperref


% WITH hyperref, uncomment the following 5 lines:
\usepackage[ps2pdf]{hyperref}
\makeatletter
  \renewcommand{\printlandscape}{%
    \def\special at paper{\the\paperheight,\the\paperwidth}}% with hyperref
\makeatother



% Note : vertical spacing between slideheading and text changes depending on
% whether hyperref is loaded or not!
% Occurs with \slideheading, not with \makeslideheading (but no ToC then)
