Hi Ann,
I'm currently using the newest stable (2.5.0.26074), but it didn't help.
I don't have Helen's book (and I'm not sure if it's available in Czech
republic yet), so I can't study that chapter.
BTW - we've already discussed this behaviour few months ago. But that
time I was using version 2.1.4.18308.
