Hi Mattias, You're welcome. It actually helped me gain insight in the workings
of the in-graph Timeline component, since that started to behave eratically
(having later entries appearing as previous entries). It took some time before
I realized the problem was in kernel and not in Timeline. Altogether a valuable
excercise. :-)
For now I will stick to M.03, but will test against SNAPSHOT next week. Have
you updated M.04 as it is available for download? Niels> Date: Fri, 17 Jun 2011
