I have updated KMListBox. It now has language support for the listbox control and has localizations for the macro. Everything is included in KMListBox.7z at
http://www.perigee.net/~jmd8421r/KMListBox.7z
All the documentation is included in the KMListBox.htm file. Languages supported are English, French, Spanish, and German. There are easy instructions on how to support other languages. The source code for the KMListBox.exe file is also included.
Extract the contents of KMListBox.7z to your user macro folder.
