donno if the following is correlated, otherwise there is another problem I
guess :-)
I attached a strace of elog, hope you'll find it useful.

- Irestarted the daemon
- attached strace to it
- requested the list for a testin logbook, few entries some quite big images 
  (two thumbnails, the other are old images get resized my the browser)
- repeted previous point a couple of times
- press F5 (mozilla-firefox)  the browser hangs 4ever
- stop the load
- repeat point 3, all right
- F5 => hangs
- F5 => hangs

there should be some problem, may be in the socket ?

Can you send me one of this old xxxxxxa.log files which causes that crash, I can then fix
it in elogd.c ...

I tried to rise the problem with konqueror, and all works nice... running
mozilla-firefox gives the problem instead (also running the test at the same time), so
there should be something in firefox or in the interaction between firefox and elog.
I'll send you one of the elog giving the problems so you can test by yourself as you
asked.

btw:
http://midas.psi.ch/elogs/Forum/?mode=full&attach=1  does not gives any problem to me
even running firefox. so the problem may be in some my elog.cong parameter ...

running ethereal I found a bug, hope this is the problem hanging my firefox (I think
we have a good chance it is :-P)

when I have thuimbs enabled, elog returns for the ".thumb" (or ".whatever".. thumb's
extension should be transparent to elog .. uhm... it can't be .. this is a problem)

anyway, having attached a pdf (a big one) and aving attachment display enabled (with
my thumbnails generated by my script)  elog returns for the displayed thumb a
Content-Type for application/x-pdf, instead of the correct image/jpeg. I think this is
the problem.

The only way for elog to know what is the correc\t content type for thumbnails is to
get it from a configuration parameter, becouse it is a chioce of the external script
used to generate them to choose the type of thumbs (jpeg, png, gif ... )
One conf parameter defaulting to jpeg may be the solution

First, find out under which account the daemon is running. It you account if
you start it interactively, if you installed from the RPM, an account "elog" is
created. Then make sure that the account under which elogd is running has write
access to the ./logbooks/Linux/ directory. One common problem is that people
start the daemon the first time under their account, which causes elogd to
create the logbook directory under the user name. If elogd is later started
under the account "elog" this one of course does not have access to the
directory. A

chown -R elog.elog /usr/local/elog/

issued as root could help in that case. Please replace /usr/local/elog with the
directory where elog is installed.

If the wrap=soft is used, users tend to enter very long lines (without 
hitting return in between). If this line then gets displayed, it can be very 
wide and the user has to horizontally scroll the browser window. What I can 
do is in the display (not the entry) to concatenate URLs which are separated 
only by a CR/LF. But you then have some cases where you have an URL to the 
end of the line, then some other text starting on the next line, which then 
get concatenated falsely (unless you use some clever code which scans 
for ".html" or "xxx/xxx" or something like that.

You always had the option "Message width = xx" to change the width on the 
text box, and I added in V 2.2.2 the parameter "Message height = xx" where 
you can change the 20 to something else.

Greetings,

I was wondering, is it possible to wrap lines in the config file ?

I have to add a dropdown lost which is kinda long and typing everything on one line will make ik kinda unreadable.
Somehow wrapping the line so each entry will get on a separate line would make it much better readable. (which
makes less errors).

What I do is to use an editor with automatic wrapping functions, like the free PSPad editor. It nicely wraps line and indicates that:
