     - MUIV_NListtree_MultiSelect_Shifted now works as expected

     - After deleting an entry,  the old entry  remains internally  active.
       Using this entry crashed the machine. Fixed!

       Fixed
     - Deleting  an  entry without  entries  in  the list  caused recursive
       function calling and stack overflow ;-) Fixed!

       Fixed!
