Thanks for the explanation. So will the OWBSlave always be needed as a kind of "big fat library" or do you plan to include the functionality to Iris step by step and some day do not need OWBSlave anymore?
OWBSlave opens as soon as you click a mail to read and open?
Would the OWBSlave also work on Efikas as a standalone? There has not been a small OWB version for a long time.
