I don't understand. Please describe what happens and how it differs from your expectations. Try to be precise, avoid using "it" after introducing several widgets as it's unclear which one it refers to.
Also, try to post runnable code. I can't find Tk::ListBox3 anywhere.
Moreover, you mentioned an error in the first post. What error was that?
map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
