Just upgraded from stable running 2.5.2-2 to 2.5.9-2 in case of the usable
Duplicate function. After the problem discribed below i made a new, clean
installation again and played araound with the demo logbook, copying my
testlogbook (part of a real used and under 2.5.2-2 working logbook) into the
demo cfg file. 

ia figured out two serious problems:

1. If I copy the following section to the global into the demo lgbook,
elogd.exe crashes emediatly ewhile starting as a prozess:

[global]
Language = German
Theme = default
logbook tabs = 1
main tab = INHALT
welcome title = <b><big>Ulrich Rolf Trüssel</big></b>

Suppress Email on Edit = 0

Reverse sort = 1

2. problem (the ting) that made me playing with teh demo cfg:
There are totally 8 logbooks running, but just one has this strange problem
of not giving a link to to the datasets in full and summary mode. I cutted
down all the stuff back to this only lines:

and got still the same problem. if i create a new logbook it will works,
also ut works under 2.5.2-2 but not longer under 2.5.3 up (even not
2.5.9-2). any idea? mening this may be a VERY basic logbook... trued with
list display etc. around, nothinh happen. Need to go back to 2.5.2-2 where
this wasn't a problem? 

thanjs for any idea of this to problems...
