----------------------
-- The Acknowledge Message is now included and working (there is a small bug when switching frfom an Ack Msg to an Asynch Msg resulting in a warning => not so problematic)
-- Changed some symbols
-- Updated the Help window

----------------------
-- The Asynch+Dialog version is also working
-- Corrected very nasty bug which appeared when switching between PVDialog and Return Msg: LV got completely stuck. I could solve this by change the inheritance before (!) building the Do.vi
-- Correted (old?) bug in the CopyClass.vi: Even if a VI from the template class is newly copied to the Msg folder he will reset it. I had problems that it could happen that some old files were still hanging around in memory...
-- Switching between the two different Dialog versions is working: He will only overwrite the Configure Dialog.vi if the new type is different from the old one. This is included to minimize the work the user has to do at the FP
-- Included the Ack-Msg button (has no function yet)
