[claus]

Ok, I am not a developer, so I dont want to "be too loud" (?), ... It is possible to sync via Apples interface and use their framework (sorry for my wording, but I think you understand me), BusyCal and QuickCal show this, because they use it, at least it works.
Sad, that it seems to be not so important for users and OG to update the sync rountine in OF.
Anywas, have to find a solution how to handle my ToDos... Best is to work on and finish them :-).
