-- Corrected an error in the Build Send.vi which occurred when a message should be created without attribute data (in fact there was a case structure missing).
-- Removed the Template.lvlib: This resulted in problems when a second message should be created because he complained that the library was still locked.
-- In the Main.vi: Included an Error dialog after each loop of the User Event Structure.
-- Added a symbol in the TreeControl for entries whose messages where just created
-- Corrected small error with the Progress bar
