V2.1 - The following issues have now been fixed:

• If you use both the extended lookup and the multiple selection popup on one form and you don't close the one or the other before clicking another field with popup, the windows aren't cleared properly
  
• The height of the multiple selection popup window exceeds the search popup window by 2 pixels
  
• The Name Picker wasn't able to handle special characters (like é, ü etc.)
  
• Doubleclicking a name in the left window when using multiple name picker would insert that name in the field instead of adding it to the right window
  
  
  
  I also changed the multiple popup window to put all buttons in one location to improve usability
